Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497098, here are decompositions:
- 97 + 31497001 = 31497098
- 109 + 31496989 = 31497098
- 151 + 31496947 = 31497098
- 181 + 31496917 = 31497098
- 271 + 31496827 = 31497098
- 307 + 31496791 = 31497098
- 379 + 31496719 = 31497098
- 421 + 31496677 = 31497098
Showing the first eight; more decompositions exist.
