Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518496, here are decompositions:
- 5 + 31518491 = 31518496
- 29 + 31518467 = 31518496
- 167 + 31518329 = 31518496
- 257 + 31518239 = 31518496
- 587 + 31517909 = 31518496
- 617 + 31517879 = 31518496
- 773 + 31517723 = 31518496
- 797 + 31517699 = 31518496
Showing the first eight; more decompositions exist.
