Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739818, here are decompositions:

7 + 8739811 = 8739818
79 + 8739739 = 8739818
97 + 8739721 = 8739818
151 + 8739667 = 8739818
181 + 8739637 = 8739818
211 + 8739607 = 8739818
337 + 8739481 = 8739818
421 + 8739397 = 8739818

Showing the first eight; more decompositions exist.
