Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742772, here are decompositions:

83 + 8742689 = 8742772
149 + 8742623 = 8742772
419 + 8742353 = 8742772
509 + 8742263 = 8742772
761 + 8742011 = 8742772
821 + 8741951 = 8742772
839 + 8741933 = 8742772
911 + 8741861 = 8742772

Showing the first eight; more decompositions exist.
