Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529664, here are decompositions:
- 13 + 31529651 = 31529664
- 41 + 31529623 = 31529664
- 71 + 31529593 = 31529664
- 97 + 31529567 = 31529664
- 107 + 31529557 = 31529664
- 113 + 31529551 = 31529664
- 157 + 31529507 = 31529664
- 193 + 31529471 = 31529664
Showing the first eight; more decompositions exist.
