Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741730, here are decompositions:

31 + 8741699 = 8741730
43 + 8741687 = 8741730
47 + 8741683 = 8741730
89 + 8741641 = 8741730
167 + 8741563 = 8741730
197 + 8741533 = 8741730
227 + 8741503 = 8741730
251 + 8741479 = 8741730

Showing the first eight; more decompositions exist.
