Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497044, here are decompositions:
- 37 + 31497007 = 31497044
- 43 + 31497001 = 31497044
- 67 + 31496977 = 31497044
- 97 + 31496947 = 31497044
- 127 + 31496917 = 31497044
- 181 + 31496863 = 31497044
- 367 + 31496677 = 31497044
- 373 + 31496671 = 31497044
Showing the first eight; more decompositions exist.
