Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508524, here are decompositions:
- 17 + 31508507 = 31508524
- 71 + 31508453 = 31508524
- 107 + 31508417 = 31508524
- 293 + 31508231 = 31508524
- 347 + 31508177 = 31508524
- 353 + 31508171 = 31508524
- 431 + 31508093 = 31508524
- 521 + 31508003 = 31508524
Showing the first eight; more decompositions exist.
