Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497370, here are decompositions:
- 11 + 31497359 = 31497370
- 17 + 31497353 = 31497370
- 29 + 31497341 = 31497370
- 71 + 31497299 = 31497370
- 83 + 31497287 = 31497370
- 449 + 31496921 = 31497370
- 587 + 31496783 = 31497370
- 677 + 31496693 = 31497370
Showing the first eight; more decompositions exist.
