Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678774, here are decompositions:

61 + 8678713 = 8678774
67 + 8678707 = 8678774
73 + 8678701 = 8678774
103 + 8678671 = 8678774
193 + 8678581 = 8678774
421 + 8678353 = 8678774
463 + 8678311 = 8678774
571 + 8678203 = 8678774

Showing the first eight; more decompositions exist.
