Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457470, here are decompositions:
- 17 + 31457453 = 31457470
- 59 + 31457411 = 31457470
- 167 + 31457303 = 31457470
- 173 + 31457297 = 31457470
- 269 + 31457201 = 31457470
- 311 + 31457159 = 31457470
- 389 + 31457081 = 31457470
- 419 + 31457051 = 31457470
Showing the first eight; more decompositions exist.
