Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668778, here are decompositions:

37 + 8668741 = 8668778
67 + 8668711 = 8668778
229 + 8668549 = 8668778
277 + 8668501 = 8668778
397 + 8668381 = 8668778
409 + 8668369 = 8668778
421 + 8668357 = 8668778
499 + 8668279 = 8668778

Showing the first eight; more decompositions exist.
