Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476730, here are decompositions:
- 3 + 31476727 = 31476730
- 107 + 31476623 = 31476730
- 137 + 31476593 = 31476730
- 179 + 31476551 = 31476730
- 269 + 31476461 = 31476730
- 281 + 31476449 = 31476730
- 293 + 31476437 = 31476730
- 317 + 31476413 = 31476730
Showing the first eight; more decompositions exist.
