Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742808, here are decompositions:

29 + 8742779 = 8742808
131 + 8742677 = 8742808
257 + 8742551 = 8742808
311 + 8742497 = 8742808
359 + 8742449 = 8742808
449 + 8742359 = 8742808
461 + 8742347 = 8742808
491 + 8742317 = 8742808

Showing the first eight; more decompositions exist.
