Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742670, here are decompositions:

17 + 8742653 = 8742670
47 + 8742623 = 8742670
173 + 8742497 = 8742670
269 + 8742401 = 8742670
311 + 8742359 = 8742670
317 + 8742353 = 8742670
353 + 8742317 = 8742670
509 + 8742161 = 8742670

Showing the first eight; more decompositions exist.
