Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739386, here are decompositions:

37 + 8739349 = 8739386
193 + 8739193 = 8739386
199 + 8739187 = 8739386
223 + 8739163 = 8739386
307 + 8739079 = 8739386
379 + 8739007 = 8739386
457 + 8738929 = 8739386
547 + 8738839 = 8739386

Showing the first eight; more decompositions exist.
