Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542246, here are decompositions:
- 79 + 542167 = 542246
- 97 + 542149 = 542246
- 127 + 542119 = 542246
- 163 + 542083 = 542246
- 193 + 542053 = 542246
- 223 + 542023 = 542246
- 409 + 541837 = 542246
- 487 + 541759 = 542246
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 542,246 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 542246 first appears in π at position 739,302 of the decimal expansion (the 739,302ordinal-suffix:nd 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.
