Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744520, here are decompositions:

7 + 8744513 = 8744520
13 + 8744507 = 8744520
23 + 8744497 = 8744520
53 + 8744467 = 8744520
61 + 8744459 = 8744520
73 + 8744447 = 8744520
97 + 8744423 = 8744520
101 + 8744419 = 8744520

Showing the first eight; more decompositions exist.
