Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145054, here are decompositions:
- 11 + 145043 = 145054
- 17 + 145037 = 145054
- 23 + 145031 = 145054
- 47 + 145007 = 145054
- 71 + 144983 = 145054
- 113 + 144941 = 145054
- 137 + 144917 = 145054
- 167 + 144887 = 145054
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 145,054 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 145054 first appears in π at position 119,806 of the decimal expansion (the 119,806ordinal-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.
