Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758580, here are decompositions:

3 + 8758577 = 8758580
7 + 8758573 = 8758580
31 + 8758549 = 8758580
43 + 8758537 = 8758580
67 + 8758513 = 8758580
73 + 8758507 = 8758580
79 + 8758501 = 8758580
97 + 8758483 = 8758580

Showing the first eight; more decompositions exist.
