Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707538, here are decompositions:

61 + 8707477 = 8707538
109 + 8707429 = 8707538
181 + 8707357 = 8707538
211 + 8707327 = 8707538
331 + 8707207 = 8707538
349 + 8707189 = 8707538
379 + 8707159 = 8707538
571 + 8706967 = 8707538

Showing the first eight; more decompositions exist.
