Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702572, here are decompositions:

3 + 8702569 = 8702572
29 + 8702543 = 8702572
83 + 8702489 = 8702572
89 + 8702483 = 8702572
113 + 8702459 = 8702572
239 + 8702333 = 8702572
293 + 8702279 = 8702572
383 + 8702189 = 8702572

Showing the first eight; more decompositions exist.
