Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641004, here are decompositions:

37 + 8640967 = 8641004
181 + 8640823 = 8641004
223 + 8640781 = 8641004
271 + 8640733 = 8641004
313 + 8640691 = 8641004
457 + 8640547 = 8641004
523 + 8640481 = 8641004
577 + 8640427 = 8641004

Showing the first eight; more decompositions exist.
