Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742230, here are decompositions:

37 + 8742193 = 8742230
43 + 8742187 = 8742230
61 + 8742169 = 8742230
73 + 8742157 = 8742230
97 + 8742133 = 8742230
109 + 8742121 = 8742230
127 + 8742103 = 8742230
163 + 8742067 = 8742230

Showing the first eight; more decompositions exist.
