Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744986, here are decompositions:

17 + 8744969 = 8744986
59 + 8744927 = 8744986
83 + 8744903 = 8744986
149 + 8744837 = 8744986
167 + 8744819 = 8744986
269 + 8744717 = 8744986
359 + 8744627 = 8744986
449 + 8744537 = 8744986

Showing the first eight; more decompositions exist.
