Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672442, here are decompositions:

13 + 8672429 = 8672442
19 + 8672423 = 8672442
61 + 8672381 = 8672442
89 + 8672353 = 8672442
109 + 8672333 = 8672442
179 + 8672263 = 8672442
239 + 8672203 = 8672442
241 + 8672201 = 8672442

Showing the first eight; more decompositions exist.
