Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744740, here are decompositions:

3 + 8744737 = 8744740
23 + 8744717 = 8744740
29 + 8744711 = 8744740
113 + 8744627 = 8744740
227 + 8744513 = 8744740
233 + 8744507 = 8744740
281 + 8744459 = 8744740
293 + 8744447 = 8744740

Showing the first eight; more decompositions exist.
