Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498656, here are decompositions:
- 17 + 31498639 = 31498656
- 97 + 31498559 = 31498656
- 107 + 31498549 = 31498656
- 109 + 31498547 = 31498656
- 127 + 31498529 = 31498656
- 139 + 31498517 = 31498656
- 157 + 31498499 = 31498656
- 193 + 31498463 = 31498656
Showing the first eight; more decompositions exist.
