Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156218, here are decompositions:

61 + 156157 = 156218
67 + 156151 = 156218
79 + 156139 = 156218
109 + 156109 = 156218
157 + 156061 = 156218
199 + 156019 = 156218
211 + 156007 = 156218
331 + 155887 = 156218

Showing the first eight; more decompositions exist.
