Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672580, here are decompositions:

17 + 8672563 = 8672580
19 + 8672561 = 8672580
29 + 8672551 = 8672580
41 + 8672539 = 8672580
53 + 8672527 = 8672580
61 + 8672519 = 8672580
67 + 8672513 = 8672580
71 + 8672509 = 8672580

Showing the first eight; more decompositions exist.
