Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37820, here are decompositions:
- 7 + 37813 = 37820
- 37 + 37783 = 37820
- 73 + 37747 = 37820
- 103 + 37717 = 37820
- 127 + 37693 = 37820
- 157 + 37663 = 37820
- 163 + 37657 = 37820
- 229 + 37591 = 37820
Showing the first eight; more decompositions exist.
