Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743420, here are decompositions:

3 + 8743417 = 8743420
11 + 8743409 = 8743420
41 + 8743379 = 8743420
53 + 8743367 = 8743420
71 + 8743349 = 8743420
89 + 8743331 = 8743420
251 + 8743169 = 8743420
281 + 8743139 = 8743420

Showing the first eight; more decompositions exist.
