Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744688, here are decompositions:

5 + 8744683 = 8744688
61 + 8744627 = 8744688
89 + 8744599 = 8744688
131 + 8744557 = 8744688
137 + 8744551 = 8744688
151 + 8744537 = 8744688
181 + 8744507 = 8744688
191 + 8744497 = 8744688

Showing the first eight; more decompositions exist.
