Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461790, here are decompositions:
- 11 + 31461779 = 31461790
- 29 + 31461761 = 31461790
- 47 + 31461743 = 31461790
- 53 + 31461737 = 31461790
- 137 + 31461653 = 31461790
- 149 + 31461641 = 31461790
- 233 + 31461557 = 31461790
- 257 + 31461533 = 31461790
Showing the first eight; more decompositions exist.
