Goldbach decomposition

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.
