Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744386, here are decompositions:

89 + 8744297 = 8744386
179 + 8744207 = 8744386
197 + 8744189 = 8744386
257 + 8744129 = 8744386
353 + 8744033 = 8744386
383 + 8744003 = 8744386
389 + 8743997 = 8744386
449 + 8743937 = 8744386

Showing the first eight; more decompositions exist.
