Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37218, here are decompositions:
- 17 + 37201 = 37218
- 19 + 37199 = 37218
- 29 + 37189 = 37218
- 37 + 37181 = 37218
- 47 + 37171 = 37218
- 59 + 37159 = 37218
- 79 + 37139 = 37218
- 101 + 37117 = 37218
Showing the first eight; more decompositions exist.
