Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486708, here are decompositions:
- 47 + 31486661 = 31486708
- 137 + 31486571 = 31486708
- 179 + 31486529 = 31486708
- 251 + 31486457 = 31486708
- 257 + 31486451 = 31486708
- 317 + 31486391 = 31486708
- 359 + 31486349 = 31486708
- 401 + 31486307 = 31486708
Showing the first eight; more decompositions exist.
