Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624406, here are decompositions:
- 19 + 31624387 = 31624406
- 43 + 31624363 = 31624406
- 67 + 31624339 = 31624406
- 277 + 31624129 = 31624406
- 337 + 31624069 = 31624406
- 439 + 31623967 = 31624406
- 739 + 31623667 = 31624406
- 883 + 31623523 = 31624406
Showing the first eight; more decompositions exist.
