Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469742, here are decompositions:
- 19 + 469723 = 469742
- 181 + 469561 = 469742
- 199 + 469543 = 469742
- 241 + 469501 = 469742
- 313 + 469429 = 469742
- 331 + 469411 = 469742
- 373 + 469369 = 469742
- 379 + 469363 = 469742
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 469,742 and was likely granted around 1891.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
