Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597516, here are decompositions:
- 23 + 31597493 = 31597516
- 149 + 31597367 = 31597516
- 179 + 31597337 = 31597516
- 233 + 31597283 = 31597516
- 263 + 31597253 = 31597516
- 317 + 31597199 = 31597516
- 389 + 31597127 = 31597516
- 593 + 31596923 = 31597516
Showing the first eight; more decompositions exist.
