Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744178, here are decompositions:

29 + 8744149 = 8744178
97 + 8744081 = 8744178
137 + 8744041 = 8744178
181 + 8743997 = 8744178
197 + 8743981 = 8744178
241 + 8743937 = 8744178
277 + 8743901 = 8744178
409 + 8743769 = 8744178

Showing the first eight; more decompositions exist.
