Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678572, here are decompositions:

53 + 8678519 = 8678572
173 + 8678399 = 8678572
179 + 8678393 = 8678572
233 + 8678339 = 8678572
239 + 8678333 = 8678572
359 + 8678213 = 8678572
431 + 8678141 = 8678572
443 + 8678129 = 8678572

Showing the first eight; more decompositions exist.
