Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758572, here are decompositions:

23 + 8758549 = 8758572
59 + 8758513 = 8758572
61 + 8758511 = 8758572
71 + 8758501 = 8758572
73 + 8758499 = 8758572
89 + 8758483 = 8758572
113 + 8758459 = 8758572
139 + 8758433 = 8758572

Showing the first eight; more decompositions exist.
