Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742416, here are decompositions:

37 + 8742379 = 8742416
103 + 8742313 = 8742416
157 + 8742259 = 8742416
223 + 8742193 = 8742416
229 + 8742187 = 8742416
283 + 8742133 = 8742416
313 + 8742103 = 8742416
349 + 8742067 = 8742416

Showing the first eight; more decompositions exist.
