Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726684, here are decompositions:

7 + 8726677 = 8726684
13 + 8726671 = 8726684
37 + 8726647 = 8726684
73 + 8726611 = 8726684
97 + 8726587 = 8726684
151 + 8726533 = 8726684
157 + 8726527 = 8726684
163 + 8726521 = 8726684

Showing the first eight; more decompositions exist.
