Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672544, here are decompositions:

5 + 8672539 = 8672544
17 + 8672527 = 8672544
31 + 8672513 = 8672544
43 + 8672501 = 8672544
61 + 8672483 = 8672544
73 + 8672471 = 8672544
103 + 8672441 = 8672544
137 + 8672407 = 8672544

Showing the first eight; more decompositions exist.
