Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475684, here are decompositions:
- 3 + 31475681 = 31475684
- 7 + 31475677 = 31475684
- 61 + 31475623 = 31475684
- 73 + 31475611 = 31475684
- 103 + 31475581 = 31475684
- 193 + 31475491 = 31475684
- 241 + 31475443 = 31475684
- 277 + 31475407 = 31475684
Showing the first eight; more decompositions exist.
