Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146480, here are decompositions:
- 3 + 146477 = 146480
- 31 + 146449 = 146480
- 43 + 146437 = 146480
- 73 + 146407 = 146480
- 97 + 146383 = 146480
- 157 + 146323 = 146480
- 163 + 146317 = 146480
- 181 + 146299 = 146480
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 146,480 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 146480 first appears in π at position 223,025 of the decimal expansion (the 223,025ordinal-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.
