Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707478, here are decompositions:

127 + 8707351 = 8707478
151 + 8707327 = 8707478
271 + 8707207 = 8707478
331 + 8707147 = 8707478
421 + 8707057 = 8707478
457 + 8707021 = 8707478
499 + 8706979 = 8707478
541 + 8706937 = 8707478

Showing the first eight; more decompositions exist.
