Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682642, here are decompositions:

53 + 8682589 = 8682642
83 + 8682559 = 8682642
109 + 8682533 = 8682642
149 + 8682493 = 8682642
229 + 8682413 = 8682642
233 + 8682409 = 8682642
239 + 8682403 = 8682642
251 + 8682391 = 8682642

Showing the first eight; more decompositions exist.
