Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461590, here are decompositions:
- 19 + 31461571 = 31461590
- 37 + 31461553 = 31461590
- 67 + 31461523 = 31461590
- 73 + 31461517 = 31461590
- 103 + 31461487 = 31461590
- 109 + 31461481 = 31461590
- 163 + 31461427 = 31461590
- 229 + 31461361 = 31461590
Showing the first eight; more decompositions exist.
