Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517458, here are decompositions:
- 17 + 31517441 = 31517458
- 41 + 31517417 = 31517458
- 47 + 31517411 = 31517458
- 59 + 31517399 = 31517458
- 191 + 31517267 = 31517458
- 227 + 31517231 = 31517458
- 251 + 31517207 = 31517458
- 419 + 31517039 = 31517458
Showing the first eight; more decompositions exist.
