Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726778, here are decompositions:

17 + 8726761 = 8726778
19 + 8726759 = 8726778
41 + 8726737 = 8726778
79 + 8726699 = 8726778
101 + 8726677 = 8726778
107 + 8726671 = 8726778
131 + 8726647 = 8726778
167 + 8726611 = 8726778

Showing the first eight; more decompositions exist.
