Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155426, here are decompositions:
- 3 + 155423 = 155426
- 13 + 155413 = 155426
- 43 + 155383 = 155426
- 109 + 155317 = 155426
- 127 + 155299 = 155426
- 157 + 155269 = 155426
- 223 + 155203 = 155426
- 307 + 155119 = 155426
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 155,426 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 155426 first appears in π at position 350,398 of the decimal expansion (the 350,398ordinal-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.
