Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713642, here are decompositions:

11 + 8713631 = 8713642
59 + 8713583 = 8713642
89 + 8713553 = 8713642
191 + 8713451 = 8713642
239 + 8713403 = 8713642
269 + 8713373 = 8713642
293 + 8713349 = 8713642
449 + 8713193 = 8713642

Showing the first eight; more decompositions exist.
