Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678078, here are decompositions:

67 + 8678011 = 8678078
127 + 8677951 = 8678078
307 + 8677771 = 8678078
397 + 8677681 = 8678078
601 + 8677477 = 8678078
691 + 8677387 = 8678078
811 + 8677267 = 8678078
907 + 8677171 = 8678078

Showing the first eight; more decompositions exist.
