Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756942, here are decompositions:

3 + 8756939 = 8756942
283 + 8756659 = 8756942
349 + 8756593 = 8756942
409 + 8756533 = 8756942
433 + 8756509 = 8756942
541 + 8756401 = 8756942
619 + 8756323 = 8756942
643 + 8756299 = 8756942

Showing the first eight; more decompositions exist.
