Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599212, here are decompositions:
- 19 + 31599193 = 31599212
- 109 + 31599103 = 31599212
- 223 + 31598989 = 31599212
- 349 + 31598863 = 31599212
- 373 + 31598839 = 31599212
- 433 + 31598779 = 31599212
- 691 + 31598521 = 31599212
- 811 + 31598401 = 31599212
Showing the first eight; more decompositions exist.
