Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719232, here are decompositions:

13 + 8719219 = 8719232
19 + 8719213 = 8719232
73 + 8719159 = 8719232
211 + 8719021 = 8719232
229 + 8719003 = 8719232
283 + 8718949 = 8719232
373 + 8718859 = 8719232
409 + 8718823 = 8719232

Showing the first eight; more decompositions exist.
