Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742826, here are decompositions:

5 + 8742821 = 8742826
47 + 8742779 = 8742826
137 + 8742689 = 8742826
149 + 8742677 = 8742826
173 + 8742653 = 8742826
467 + 8742359 = 8742826
479 + 8742347 = 8742826
509 + 8742317 = 8742826

Showing the first eight; more decompositions exist.
