Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497526, here are decompositions:
- 3 + 31497523 = 31497526
- 59 + 31497467 = 31497526
- 83 + 31497443 = 31497526
- 167 + 31497359 = 31497526
- 173 + 31497353 = 31497526
- 227 + 31497299 = 31497526
- 233 + 31497293 = 31497526
- 239 + 31497287 = 31497526
Showing the first eight; more decompositions exist.
