Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744646, here are decompositions:

19 + 8744627 = 8744646
47 + 8744599 = 8744646
83 + 8744563 = 8744646
89 + 8744557 = 8744646
109 + 8744537 = 8744646
139 + 8744507 = 8744646
149 + 8744497 = 8744646
179 + 8744467 = 8744646

Showing the first eight; more decompositions exist.
