Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628308, here are decompositions:
- 17 + 31628291 = 31628308
- 59 + 31628249 = 31628308
- 137 + 31628171 = 31628308
- 347 + 31627961 = 31628308
- 359 + 31627949 = 31628308
- 419 + 31627889 = 31628308
- 557 + 31627751 = 31628308
- 587 + 31627721 = 31628308
Showing the first eight; more decompositions exist.
