Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468228, here are decompositions:
- 5 + 31468223 = 31468228
- 17 + 31468211 = 31468228
- 59 + 31468169 = 31468228
- 131 + 31468097 = 31468228
- 227 + 31468001 = 31468228
- 317 + 31467911 = 31468228
- 419 + 31467809 = 31468228
- 461 + 31467767 = 31468228
Showing the first eight; more decompositions exist.
