Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615848, here are decompositions:
- 41 + 31615807 = 31615848
- 107 + 31615741 = 31615848
- 137 + 31615711 = 31615848
- 179 + 31615669 = 31615848
- 197 + 31615651 = 31615848
- 239 + 31615609 = 31615848
- 359 + 31615489 = 31615848
- 409 + 31615439 = 31615848
Showing the first eight; more decompositions exist.
