Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720764, here are decompositions:

71 + 8720693 = 8720764
83 + 8720681 = 8720764
137 + 8720627 = 8720764
167 + 8720597 = 8720764
233 + 8720531 = 8720764
251 + 8720513 = 8720764
281 + 8720483 = 8720764
293 + 8720471 = 8720764

Showing the first eight; more decompositions exist.
