Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146472, here are decompositions:
- 23 + 146449 = 146472
- 83 + 146389 = 146472
- 89 + 146383 = 146472
- 103 + 146369 = 146472
- 113 + 146359 = 146472
- 149 + 146323 = 146472
- 163 + 146309 = 146472
- 173 + 146299 = 146472
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 146,472 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 146472 first appears in π at position 21,988 of the decimal expansion (the 21,988ordinal-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.
