Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484216, here are decompositions:
- 7 + 31484209 = 31484216
- 13 + 31484203 = 31484216
- 37 + 31484179 = 31484216
- 73 + 31484143 = 31484216
- 157 + 31484059 = 31484216
- 397 + 31483819 = 31484216
- 409 + 31483807 = 31484216
- 457 + 31483759 = 31484216
Showing the first eight; more decompositions exist.
