Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742668, here are decompositions:

31 + 8742637 = 8742668
97 + 8742571 = 8742668
127 + 8742541 = 8742668
139 + 8742529 = 8742668
157 + 8742511 = 8742668
199 + 8742469 = 8742668
409 + 8742259 = 8742668
499 + 8742169 = 8742668

Showing the first eight; more decompositions exist.
