Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155364, here are decompositions:
- 31 + 155333 = 155364
- 37 + 155327 = 155364
- 47 + 155317 = 155364
- 61 + 155303 = 155364
- 73 + 155291 = 155364
- 113 + 155251 = 155364
- 163 + 155201 = 155364
- 173 + 155191 = 155364
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 155,364 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 155364 first appears in π at position 349,246 of the decimal expansion (the 349,246ordinal-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.
