Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476286, here are decompositions:
- 3 + 31476283 = 31476286
- 47 + 31476239 = 31476286
- 137 + 31476149 = 31476286
- 167 + 31476119 = 31476286
- 173 + 31476113 = 31476286
- 227 + 31476059 = 31476286
- 269 + 31476017 = 31476286
- 509 + 31475777 = 31476286
Showing the first eight; more decompositions exist.
