Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744170, here are decompositions:

41 + 8744129 = 8744170
89 + 8744081 = 8744170
107 + 8744063 = 8744170
137 + 8744033 = 8744170
167 + 8744003 = 8744170
173 + 8743997 = 8744170
179 + 8743991 = 8744170
233 + 8743937 = 8744170

Showing the first eight; more decompositions exist.
