Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628578, here are decompositions:

31 + 8628547 = 8628578
97 + 8628481 = 8628578
157 + 8628421 = 8628578
229 + 8628349 = 8628578
307 + 8628271 = 8628578
397 + 8628181 = 8628578
421 + 8628157 = 8628578
457 + 8628121 = 8628578

Showing the first eight; more decompositions exist.
