Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746642, here are decompositions:

5 + 8746637 = 8746642
173 + 8746469 = 8746642
251 + 8746391 = 8746642
263 + 8746379 = 8746642
383 + 8746259 = 8746642
419 + 8746223 = 8746642
449 + 8746193 = 8746642
719 + 8745923 = 8746642

Showing the first eight; more decompositions exist.
