Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663572, here are decompositions:

53 + 8663519 = 8663572
101 + 8663471 = 8663572
131 + 8663441 = 8663572
263 + 8663309 = 8663572
293 + 8663279 = 8663572
311 + 8663261 = 8663572
419 + 8663153 = 8663572
479 + 8663093 = 8663572

Showing the first eight; more decompositions exist.
