Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701572, here are decompositions:

13 + 8701559 = 8701572
41 + 8701531 = 8701572
43 + 8701529 = 8701572
53 + 8701519 = 8701572
73 + 8701499 = 8701572
79 + 8701493 = 8701572
83 + 8701489 = 8701572
149 + 8701423 = 8701572

Showing the first eight; more decompositions exist.
