Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146420, here are decompositions:
- 3 + 146417 = 146420
- 13 + 146407 = 146420
- 31 + 146389 = 146420
- 37 + 146383 = 146420
- 61 + 146359 = 146420
- 73 + 146347 = 146420
- 97 + 146323 = 146420
- 103 + 146317 = 146420
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 146,420 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 146420 first appears in π at position 979,030 of the decimal expansion (the 979,030ordinal-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.
