Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639084, here are decompositions:

73 + 8639011 = 8639084
151 + 8638933 = 8639084
193 + 8638891 = 8639084
241 + 8638843 = 8639084
277 + 8638807 = 8639084
397 + 8638687 = 8639084
457 + 8638627 = 8639084
463 + 8638621 = 8639084

Showing the first eight; more decompositions exist.
