Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707442, here are decompositions:

13 + 8707429 = 8707442
109 + 8707333 = 8707442
223 + 8707219 = 8707442
283 + 8707159 = 8707442
349 + 8707093 = 8707442
421 + 8707021 = 8707442
439 + 8707003 = 8707442
463 + 8706979 = 8707442

Showing the first eight; more decompositions exist.
