Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721348, here are decompositions:

19 + 8721329 = 8721348
37 + 8721311 = 8721348
67 + 8721281 = 8721348
79 + 8721269 = 8721348
89 + 8721259 = 8721348
109 + 8721239 = 8721348
151 + 8721197 = 8721348
157 + 8721191 = 8721348

Showing the first eight; more decompositions exist.
