Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490230, here are decompositions:
- 3 + 31490227 = 31490230
- 41 + 31490189 = 31490230
- 131 + 31490099 = 31490230
- 137 + 31490093 = 31490230
- 173 + 31490057 = 31490230
- 281 + 31489949 = 31490230
- 311 + 31489919 = 31490230
- 347 + 31489883 = 31490230
Showing the first eight; more decompositions exist.
