Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628542, here are decompositions:

61 + 8628481 = 8628542
79 + 8628463 = 8628542
193 + 8628349 = 8628542
271 + 8628271 = 8628542
421 + 8628121 = 8628542
523 + 8628019 = 8628542
631 + 8627911 = 8628542
691 + 8627851 = 8628542

Showing the first eight; more decompositions exist.
