Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744664, here are decompositions:

37 + 8744627 = 8744664
53 + 8744611 = 8744664
101 + 8744563 = 8744664
107 + 8744557 = 8744664
113 + 8744551 = 8744664
127 + 8744537 = 8744664
151 + 8744513 = 8744664
157 + 8744507 = 8744664

Showing the first eight; more decompositions exist.
