Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742264, here are decompositions:
- 5 + 8742259 = 8742264
- 67 + 8742197 = 8742264
- 71 + 8742193 = 8742264
- 103 + 8742161 = 8742264
- 107 + 8742157 = 8742264
- 131 + 8742133 = 8742264
- 197 + 8742067 = 8742264
- 227 + 8742037 = 8742264
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,742,264 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 8742264 first appears in π at position 293,793 of the decimal expansion (the 293,793ordinal-suffix:rd digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
