Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742736, here are decompositions:

47 + 8742689 = 8742736
59 + 8742677 = 8742736
83 + 8742653 = 8742736
113 + 8742623 = 8742736
239 + 8742497 = 8742736
383 + 8742353 = 8742736
389 + 8742347 = 8742736
419 + 8742317 = 8742736

Showing the first eight; more decompositions exist.
