Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707742, here are decompositions:

31 + 8707711 = 8707742
73 + 8707669 = 8707742
139 + 8707603 = 8707742
151 + 8707591 = 8707742
163 + 8707579 = 8707742
313 + 8707429 = 8707742
349 + 8707393 = 8707742
409 + 8707333 = 8707742

Showing the first eight; more decompositions exist.
