Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641832, here are decompositions:

13 + 8641819 = 8641832
163 + 8641669 = 8641832
181 + 8641651 = 8641832
211 + 8641621 = 8641832
229 + 8641603 = 8641832
313 + 8641519 = 8641832
379 + 8641453 = 8641832
523 + 8641309 = 8641832

Showing the first eight; more decompositions exist.
