Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672520, here are decompositions:

7 + 8672513 = 8672520
11 + 8672509 = 8672520
19 + 8672501 = 8672520
37 + 8672483 = 8672520
79 + 8672441 = 8672520
97 + 8672423 = 8672520
113 + 8672407 = 8672520
139 + 8672381 = 8672520

Showing the first eight; more decompositions exist.
