Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483760, here are decompositions:
- 37 + 31483723 = 31483760
- 97 + 31483663 = 31483760
- 163 + 31483597 = 31483760
- 211 + 31483549 = 31483760
- 307 + 31483453 = 31483760
- 313 + 31483447 = 31483760
- 331 + 31483429 = 31483760
- 409 + 31483351 = 31483760
Showing the first eight; more decompositions exist.
