Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942864, here are decompositions:
- 5 + 942859 = 942864
- 7 + 942857 = 942864
- 11 + 942853 = 942864
- 17 + 942847 = 942864
- 37 + 942827 = 942864
- 53 + 942811 = 942864
- 101 + 942763 = 942864
- 137 + 942727 = 942864
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 942,864 and was likely granted around 1909.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 942864 first appears in π at position 370,118 of the decimal expansion (the 370,118ordinal-suffix:th 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.
