Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476900, here are decompositions:
- 19 + 31476881 = 31476900
- 29 + 31476871 = 31476900
- 47 + 31476853 = 31476900
- 53 + 31476847 = 31476900
- 71 + 31476829 = 31476900
- 79 + 31476821 = 31476900
- 101 + 31476799 = 31476900
- 157 + 31476743 = 31476900
Showing the first eight; more decompositions exist.
