Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589728, here are decompositions:
- 17 + 31589711 = 31589728
- 167 + 31589561 = 31589728
- 389 + 31589339 = 31589728
- 431 + 31589297 = 31589728
- 641 + 31589087 = 31589728
- 659 + 31589069 = 31589728
- 701 + 31589027 = 31589728
- 881 + 31588847 = 31589728
Showing the first eight; more decompositions exist.
