Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719072, here are decompositions:

23 + 8719049 = 8719072
41 + 8719031 = 8719072
191 + 8718881 = 8719072
233 + 8718839 = 8719072
239 + 8718833 = 8719072
269 + 8718803 = 8719072
293 + 8718779 = 8719072
491 + 8718581 = 8719072

Showing the first eight; more decompositions exist.
