Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37220, here are decompositions:
- 3 + 37217 = 37220
- 19 + 37201 = 37220
- 31 + 37189 = 37220
- 61 + 37159 = 37220
- 97 + 37123 = 37220
- 103 + 37117 = 37220
- 163 + 37057 = 37220
- 181 + 37039 = 37220
Showing the first eight; more decompositions exist.
