Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37818, here are decompositions:
- 5 + 37813 = 37818
- 7 + 37811 = 37818
- 19 + 37799 = 37818
- 37 + 37781 = 37818
- 71 + 37747 = 37818
- 101 + 37717 = 37818
- 127 + 37691 = 37818
- 199 + 37619 = 37818
Showing the first eight; more decompositions exist.
