Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475908, here are decompositions:
- 59 + 31475849 = 31475908
- 131 + 31475777 = 31475908
- 137 + 31475771 = 31475908
- 227 + 31475681 = 31475908
- 239 + 31475669 = 31475908
- 311 + 31475597 = 31475908
- 419 + 31475489 = 31475908
- 449 + 31475459 = 31475908
Showing the first eight; more decompositions exist.
