Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658742, here are decompositions:

3 + 8658739 = 8658742
83 + 8658659 = 8658742
89 + 8658653 = 8658742
173 + 8658569 = 8658742
311 + 8658431 = 8658742
359 + 8658383 = 8658742
419 + 8658323 = 8658742
509 + 8658233 = 8658742

Showing the first eight; more decompositions exist.
