Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739628, here are decompositions:

5 + 8739623 = 8739628
11 + 8739617 = 8739628
137 + 8739491 = 8739628
197 + 8739431 = 8739628
239 + 8739389 = 8739628
269 + 8739359 = 8739628
347 + 8739281 = 8739628
419 + 8739209 = 8739628

Showing the first eight; more decompositions exist.
