Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744518, here are decompositions:

5 + 8744513 = 8744518
11 + 8744507 = 8744518
59 + 8744459 = 8744518
71 + 8744447 = 8744518
257 + 8744261 = 8744518
311 + 8744207 = 8744518
389 + 8744129 = 8744518
521 + 8743997 = 8744518

Showing the first eight; more decompositions exist.
