Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739028, here are decompositions:

5 + 8739023 = 8739028
71 + 8738957 = 8739028
191 + 8738837 = 8739028
227 + 8738801 = 8739028
269 + 8738759 = 8739028
317 + 8738711 = 8739028
449 + 8738579 = 8739028
461 + 8738567 = 8739028

Showing the first eight; more decompositions exist.
