Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457270, here are decompositions:
- 3 + 31457267 = 31457270
- 43 + 31457227 = 31457270
- 67 + 31457203 = 31457270
- 151 + 31457119 = 31457270
- 199 + 31457071 = 31457270
- 367 + 31456903 = 31457270
- 379 + 31456891 = 31457270
- 421 + 31456849 = 31457270
Showing the first eight; more decompositions exist.
