Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629078, here are decompositions:

5 + 8629073 = 8629078
179 + 8628899 = 8629078
401 + 8628677 = 8629078
431 + 8628647 = 8629078
449 + 8628629 = 8629078
599 + 8628479 = 8629078
701 + 8628377 = 8629078
719 + 8628359 = 8629078

Showing the first eight; more decompositions exist.
