Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155064, here are decompositions:
- 17 + 155047 = 155064
- 37 + 155027 = 155064
- 47 + 155017 = 155064
- 61 + 155003 = 155064
- 73 + 154991 = 155064
- 83 + 154981 = 155064
- 127 + 154937 = 155064
- 131 + 154933 = 155064
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 155,064 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 155064 first appears in π at position 554,632 of the decimal expansion (the 554,632ordinal-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.
