Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742678, here are decompositions:

5 + 8742673 = 8742678
41 + 8742637 = 8742678
101 + 8742577 = 8742678
107 + 8742571 = 8742678
127 + 8742551 = 8742678
137 + 8742541 = 8742678
149 + 8742529 = 8742678
167 + 8742511 = 8742678

Showing the first eight; more decompositions exist.
