Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458122, here are decompositions:
- 61 + 31458061 = 31458122
- 109 + 31458013 = 31458122
- 193 + 31457929 = 31458122
- 211 + 31457911 = 31458122
- 379 + 31457743 = 31458122
- 643 + 31457479 = 31458122
- 673 + 31457449 = 31458122
- 739 + 31457383 = 31458122
Showing the first eight; more decompositions exist.
