Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497358, here are decompositions:
- 5 + 31497353 = 31497358
- 17 + 31497341 = 31497358
- 59 + 31497299 = 31497358
- 71 + 31497287 = 31497358
- 107 + 31497251 = 31497358
- 401 + 31496957 = 31497358
- 617 + 31496741 = 31497358
- 821 + 31496537 = 31497358
Showing the first eight; more decompositions exist.
