Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742832, here are decompositions:

11 + 8742821 = 8742832
53 + 8742779 = 8742832
179 + 8742653 = 8742832
281 + 8742551 = 8742832
383 + 8742449 = 8742832
431 + 8742401 = 8742832
479 + 8742353 = 8742832
569 + 8742263 = 8742832

Showing the first eight; more decompositions exist.
