Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672572, here are decompositions:

11 + 8672561 = 8672572
53 + 8672519 = 8672572
59 + 8672513 = 8672572
71 + 8672501 = 8672572
89 + 8672483 = 8672572
101 + 8672471 = 8672572
131 + 8672441 = 8672572
149 + 8672423 = 8672572

Showing the first eight; more decompositions exist.
