Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475472, here are decompositions:
- 13 + 31475459 = 31475472
- 19 + 31475453 = 31475472
- 29 + 31475443 = 31475472
- 43 + 31475429 = 31475472
- 71 + 31475401 = 31475472
- 79 + 31475393 = 31475472
- 101 + 31475371 = 31475472
- 131 + 31475341 = 31475472
Showing the first eight; more decompositions exist.
