Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663442, here are decompositions:

5 + 8663437 = 8663442
41 + 8663401 = 8663442
131 + 8663311 = 8663442
163 + 8663279 = 8663442
181 + 8663261 = 8663442
233 + 8663209 = 8663442
349 + 8663093 = 8663442
353 + 8663089 = 8663442

Showing the first eight; more decompositions exist.
