Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721052, here are decompositions:

3 + 8721049 = 8721052
23 + 8721029 = 8721052
83 + 8720969 = 8721052
233 + 8720819 = 8721052
269 + 8720783 = 8721052
281 + 8720771 = 8721052
359 + 8720693 = 8721052
521 + 8720531 = 8721052

Showing the first eight; more decompositions exist.
