Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743438, here are decompositions:

17 + 8743421 = 8743438
29 + 8743409 = 8743438
59 + 8743379 = 8743438
71 + 8743367 = 8743438
89 + 8743349 = 8743438
107 + 8743331 = 8743438
269 + 8743169 = 8743438
317 + 8743121 = 8743438

Showing the first eight; more decompositions exist.
