Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726586, here are decompositions:

13 + 8726573 = 8726586
17 + 8726569 = 8726586
53 + 8726533 = 8726586
59 + 8726527 = 8726586
79 + 8726507 = 8726586
107 + 8726479 = 8726586
137 + 8726449 = 8726586
139 + 8726447 = 8726586

Showing the first eight; more decompositions exist.
