Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672542, here are decompositions:

3 + 8672539 = 8672542
23 + 8672519 = 8672542
29 + 8672513 = 8672542
41 + 8672501 = 8672542
59 + 8672483 = 8672542
71 + 8672471 = 8672542
101 + 8672441 = 8672542
113 + 8672429 = 8672542

Showing the first eight; more decompositions exist.
