Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678012, here are decompositions:

19 + 8677993 = 8678012
61 + 8677951 = 8678012
241 + 8677771 = 8678012
331 + 8677681 = 8678012
349 + 8677663 = 8678012
613 + 8677399 = 8678012
619 + 8677393 = 8678012
751 + 8677261 = 8678012

Showing the first eight; more decompositions exist.
