Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730656, here are decompositions:

7 + 8730649 = 8730656
37 + 8730619 = 8730656
73 + 8730583 = 8730656
79 + 8730577 = 8730656
97 + 8730559 = 8730656
127 + 8730529 = 8730656
139 + 8730517 = 8730656
307 + 8730349 = 8730656

Showing the first eight; more decompositions exist.
