Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707458, here are decompositions:

29 + 8707429 = 8707458
37 + 8707421 = 8707458
79 + 8707379 = 8707458
101 + 8707357 = 8707458
107 + 8707351 = 8707458
131 + 8707327 = 8707458
181 + 8707277 = 8707458
239 + 8707219 = 8707458

Showing the first eight; more decompositions exist.
