Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744560, here are decompositions:

3 + 8744557 = 8744560
23 + 8744537 = 8744560
47 + 8744513 = 8744560
53 + 8744507 = 8744560
101 + 8744459 = 8744560
113 + 8744447 = 8744560
137 + 8744423 = 8744560
263 + 8744297 = 8744560

Showing the first eight; more decompositions exist.
