Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475664, here are decompositions:
- 41 + 31475623 = 31475664
- 53 + 31475611 = 31475664
- 67 + 31475597 = 31475664
- 83 + 31475581 = 31475664
- 173 + 31475491 = 31475664
- 193 + 31475471 = 31475664
- 211 + 31475453 = 31475664
- 257 + 31475407 = 31475664
Showing the first eight; more decompositions exist.
