Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739672, here are decompositions:

5 + 8739667 = 8739672
89 + 8739583 = 8739672
173 + 8739499 = 8739672
181 + 8739491 = 8739672
191 + 8739481 = 8739672
239 + 8739433 = 8739672
241 + 8739431 = 8739672
281 + 8739391 = 8739672

Showing the first eight; more decompositions exist.
