Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457368, here are decompositions:
- 71 + 31457297 = 31457368
- 101 + 31457267 = 31457368
- 167 + 31457201 = 31457368
- 197 + 31457171 = 31457368
- 269 + 31457099 = 31457368
- 317 + 31457051 = 31457368
- 359 + 31457009 = 31457368
- 419 + 31456949 = 31457368
Showing the first eight; more decompositions exist.
