Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744240, here are decompositions:

7 + 8744233 = 8744240
13 + 8744227 = 8744240
97 + 8744143 = 8744240
139 + 8744101 = 8744240
157 + 8744083 = 8744240
199 + 8744041 = 8744240
277 + 8743963 = 8744240
397 + 8743843 = 8744240

Showing the first eight; more decompositions exist.
