Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726138, here are decompositions:

37 + 8726101 = 8726138
139 + 8725999 = 8726138
151 + 8725987 = 8726138
307 + 8725831 = 8726138
439 + 8725699 = 8726138
457 + 8725681 = 8726138
571 + 8725567 = 8726138
607 + 8725531 = 8726138

Showing the first eight; more decompositions exist.
