Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663372, here are decompositions:

61 + 8663311 = 8663372
163 + 8663209 = 8663372
271 + 8663101 = 8663372
283 + 8663089 = 8663372
349 + 8663023 = 8663372
409 + 8662963 = 8663372
433 + 8662939 = 8663372
541 + 8662831 = 8663372

Showing the first eight; more decompositions exist.
