Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490068, here are decompositions:
- 11 + 31490057 = 31490068
- 149 + 31489919 = 31490068
- 167 + 31489901 = 31490068
- 227 + 31489841 = 31490068
- 251 + 31489817 = 31490068
- 317 + 31489751 = 31490068
- 347 + 31489721 = 31490068
- 359 + 31489709 = 31490068
Showing the first eight; more decompositions exist.
