Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645542, here are decompositions:

281 + 8645261 = 8645542
401 + 8645141 = 8645542
419 + 8645123 = 8645542
461 + 8645081 = 8645542
593 + 8644949 = 8645542
743 + 8644799 = 8645542
761 + 8644781 = 8645542
839 + 8644703 = 8645542

Showing the first eight; more decompositions exist.
