Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497074, here are decompositions:
- 3 + 31497071 = 31497074
- 67 + 31497007 = 31497074
- 73 + 31497001 = 31497074
- 97 + 31496977 = 31497074
- 127 + 31496947 = 31497074
- 157 + 31496917 = 31497074
- 211 + 31496863 = 31497074
- 283 + 31496791 = 31497074
Showing the first eight; more decompositions exist.
