Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742712, here are decompositions:

23 + 8742689 = 8742712
59 + 8742653 = 8742712
89 + 8742623 = 8742712
263 + 8742449 = 8742712
311 + 8742401 = 8742712
353 + 8742359 = 8742712
359 + 8742353 = 8742712
449 + 8742263 = 8742712

Showing the first eight; more decompositions exist.
