Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488470, here are decompositions:
- 7 + 31488463 = 31488470
- 37 + 31488433 = 31488470
- 199 + 31488271 = 31488470
- 337 + 31488133 = 31488470
- 379 + 31488091 = 31488470
- 439 + 31488031 = 31488470
- 457 + 31488013 = 31488470
- 691 + 31487779 = 31488470
Showing the first eight; more decompositions exist.
