Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743690, here are decompositions:

17 + 8743673 = 8743690
101 + 8743589 = 8743690
107 + 8743583 = 8743690
191 + 8743499 = 8743690
269 + 8743421 = 8743690
281 + 8743409 = 8743690
311 + 8743379 = 8743690
359 + 8743331 = 8743690

Showing the first eight; more decompositions exist.
