Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743828, here are decompositions:

11 + 8743817 = 8743828
59 + 8743769 = 8743828
239 + 8743589 = 8743828
257 + 8743571 = 8743828
281 + 8743547 = 8743828
419 + 8743409 = 8743828
449 + 8743379 = 8743828
461 + 8743367 = 8743828

Showing the first eight; more decompositions exist.
