Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742078, here are decompositions:

11 + 8742067 = 8742078
19 + 8742059 = 8742078
41 + 8742037 = 8742078
67 + 8742011 = 8742078
89 + 8741989 = 8742078
101 + 8741977 = 8742078
127 + 8741951 = 8742078
131 + 8741947 = 8742078

Showing the first eight; more decompositions exist.
