Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721796, here are decompositions:

23 + 8721773 = 8721796
47 + 8721749 = 8721796
59 + 8721737 = 8721796
179 + 8721617 = 8721796
197 + 8721599 = 8721796
257 + 8721539 = 8721796
263 + 8721533 = 8721796
353 + 8721443 = 8721796

Showing the first eight; more decompositions exist.
