Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742162, here are decompositions:

5 + 8742157 = 8742162
29 + 8742133 = 8742162
41 + 8742121 = 8742162
59 + 8742103 = 8742162
103 + 8742059 = 8742162
151 + 8742011 = 8742162
173 + 8741989 = 8742162
179 + 8741983 = 8742162

Showing the first eight; more decompositions exist.
