Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726520, here are decompositions:

13 + 8726507 = 8726520
41 + 8726479 = 8726520
53 + 8726467 = 8726520
59 + 8726461 = 8726520
71 + 8726449 = 8726520
73 + 8726447 = 8726520
137 + 8726383 = 8726520
139 + 8726381 = 8726520

Showing the first eight; more decompositions exist.
