Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641748, here are decompositions:

7 + 8641741 = 8641748
79 + 8641669 = 8641748
97 + 8641651 = 8641748
127 + 8641621 = 8641748
229 + 8641519 = 8641748
277 + 8641471 = 8641748
397 + 8641351 = 8641748
421 + 8641327 = 8641748

Showing the first eight; more decompositions exist.
