Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721196, here are decompositions:

5 + 8721191 = 8721196
167 + 8721029 = 8721196
227 + 8720969 = 8721196
359 + 8720837 = 8721196
389 + 8720807 = 8721196
467 + 8720729 = 8721196
503 + 8720693 = 8721196
509 + 8720687 = 8721196

Showing the first eight; more decompositions exist.
