Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457456, here are decompositions:
- 3 + 31457453 = 31457456
- 7 + 31457449 = 31457456
- 73 + 31457383 = 31457456
- 109 + 31457347 = 31457456
- 127 + 31457329 = 31457456
- 229 + 31457227 = 31457456
- 307 + 31457149 = 31457456
- 337 + 31457119 = 31457456
Showing the first eight; more decompositions exist.
