Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744290, here are decompositions:

29 + 8744261 = 8744290
47 + 8744243 = 8744290
83 + 8744207 = 8744290
101 + 8744189 = 8744290
227 + 8744063 = 8744290
257 + 8744033 = 8744290
293 + 8743997 = 8744290
353 + 8743937 = 8744290

Showing the first eight; more decompositions exist.
