Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743426, here are decompositions:

5 + 8743421 = 8743426
17 + 8743409 = 8743426
47 + 8743379 = 8743426
59 + 8743367 = 8743426
149 + 8743277 = 8743426
257 + 8743169 = 8743426
347 + 8743079 = 8743426
359 + 8743067 = 8743426

Showing the first eight; more decompositions exist.
