Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744020, here are decompositions:

17 + 8744003 = 8744020
23 + 8743997 = 8744020
29 + 8743991 = 8744020
83 + 8743937 = 8744020
101 + 8743919 = 8744020
107 + 8743913 = 8744020
137 + 8743883 = 8744020
167 + 8743853 = 8744020

Showing the first eight; more decompositions exist.
