Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642044, here are decompositions:

11 + 8642033 = 8642044
17 + 8642027 = 8642044
41 + 8642003 = 8642044
53 + 8641991 = 8642044
227 + 8641817 = 8642044
263 + 8641781 = 8642044
311 + 8641733 = 8642044
347 + 8641697 = 8642044

Showing the first eight; more decompositions exist.
