Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512698, here are decompositions:
- 67 + 31512631 = 31512698
- 97 + 31512601 = 31512698
- 199 + 31512499 = 31512698
- 367 + 31512331 = 31512698
- 409 + 31512289 = 31512698
- 439 + 31512259 = 31512698
- 487 + 31512211 = 31512698
- 499 + 31512199 = 31512698
Showing the first eight; more decompositions exist.
