Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495742, here are decompositions:
- 13 + 31495729 = 31495742
- 79 + 31495663 = 31495742
- 139 + 31495603 = 31495742
- 151 + 31495591 = 31495742
- 241 + 31495501 = 31495742
- 409 + 31495333 = 31495742
- 571 + 31495171 = 31495742
- 739 + 31495003 = 31495742
Showing the first eight; more decompositions exist.
