Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457482, here are decompositions:
- 3 + 31457479 = 31457482
- 11 + 31457471 = 31457482
- 29 + 31457453 = 31457482
- 71 + 31457411 = 31457482
- 179 + 31457303 = 31457482
- 281 + 31457201 = 31457482
- 311 + 31457171 = 31457482
- 383 + 31457099 = 31457482
Showing the first eight; more decompositions exist.
