Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744628, here are decompositions:

17 + 8744611 = 8744628
29 + 8744599 = 8744628
71 + 8744557 = 8744628
131 + 8744497 = 8744628
181 + 8744447 = 8744628
311 + 8744317 = 8744628
331 + 8744297 = 8744628
359 + 8744269 = 8744628

Showing the first eight; more decompositions exist.
