Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145084, here are decompositions:
- 41 + 145043 = 145084
- 47 + 145037 = 145084
- 53 + 145031 = 145084
- 101 + 144983 = 145084
- 167 + 144917 = 145084
- 197 + 144887 = 145084
- 293 + 144791 = 145084
- 311 + 144773 = 145084
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 145,084 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 145084 first appears in π at position 346,009 of the decimal expansion (the 346,009ordinal-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.
