Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471590, here are decompositions:
- 11 + 31471579 = 31471590
- 13 + 31471577 = 31471590
- 41 + 31471549 = 31471590
- 67 + 31471523 = 31471590
- 79 + 31471511 = 31471590
- 109 + 31471481 = 31471590
- 151 + 31471439 = 31471590
- 179 + 31471411 = 31471590
Showing the first eight; more decompositions exist.
