Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611844, here are decompositions:
- 3 + 31611841 = 31611844
- 41 + 31611803 = 31611844
- 83 + 31611761 = 31611844
- 107 + 31611737 = 31611844
- 197 + 31611647 = 31611844
- 227 + 31611617 = 31611844
- 263 + 31611581 = 31611844
- 317 + 31611527 = 31611844
Showing the first eight; more decompositions exist.
