Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743642, here are decompositions:

3 + 8743639 = 8743642
53 + 8743589 = 8743642
59 + 8743583 = 8743642
71 + 8743571 = 8743642
233 + 8743409 = 8743642
263 + 8743379 = 8743642
293 + 8743349 = 8743642
311 + 8743331 = 8743642

Showing the first eight; more decompositions exist.
