Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628446, here are decompositions:

3 + 8628443 = 8628446
97 + 8628349 = 8628446
349 + 8628097 = 8628446
397 + 8628049 = 8628446
439 + 8628007 = 8628446
499 + 8627947 = 8628446
613 + 8627833 = 8628446
733 + 8627713 = 8628446

Showing the first eight; more decompositions exist.
