Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744686, here are decompositions:

3 + 8744683 = 8744686
23 + 8744663 = 8744686
59 + 8744627 = 8744686
149 + 8744537 = 8744686
173 + 8744513 = 8744686
179 + 8744507 = 8744686
227 + 8744459 = 8744686
239 + 8744447 = 8744686

Showing the first eight; more decompositions exist.
