Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498330, here are decompositions:
- 23 + 31498307 = 31498330
- 41 + 31498289 = 31498330
- 53 + 31498277 = 31498330
- 113 + 31498217 = 31498330
- 131 + 31498199 = 31498330
- 137 + 31498193 = 31498330
- 179 + 31498151 = 31498330
- 389 + 31497941 = 31498330
Showing the first eight; more decompositions exist.
