Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497406, here are decompositions:
- 47 + 31497359 = 31497406
- 53 + 31497353 = 31497406
- 107 + 31497299 = 31497406
- 113 + 31497293 = 31497406
- 443 + 31496963 = 31497406
- 449 + 31496957 = 31497406
- 587 + 31496819 = 31497406
- 839 + 31496567 = 31497406
Showing the first eight; more decompositions exist.
