Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739090, here are decompositions:

11 + 8739079 = 8739090
37 + 8739053 = 8739090
67 + 8739023 = 8739090
83 + 8739007 = 8739090
89 + 8739001 = 8739090
127 + 8738963 = 8739090
251 + 8738839 = 8739090
277 + 8738813 = 8739090

Showing the first eight; more decompositions exist.
