Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726040, here are decompositions:

13 + 8726027 = 8726040
19 + 8726021 = 8726040
23 + 8726017 = 8726040
41 + 8725999 = 8726040
53 + 8725987 = 8726040
61 + 8725979 = 8726040
79 + 8725961 = 8726040
109 + 8725931 = 8726040

Showing the first eight; more decompositions exist.
