Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471286, here are decompositions:
- 73 + 31471213 = 31471286
- 79 + 31471207 = 31471286
- 139 + 31471147 = 31471286
- 163 + 31471123 = 31471286
- 193 + 31471093 = 31471286
- 373 + 31470913 = 31471286
- 397 + 31470889 = 31471286
- 433 + 31470853 = 31471286
Showing the first eight; more decompositions exist.
