Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639562, here are decompositions:

11 + 8639551 = 8639562
13 + 8639549 = 8639562
23 + 8639539 = 8639562
31 + 8639531 = 8639562
101 + 8639461 = 8639562
103 + 8639459 = 8639562
109 + 8639453 = 8639562
149 + 8639413 = 8639562

Showing the first eight; more decompositions exist.
