Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720962, here are decompositions:

71 + 8720891 = 8720962
179 + 8720783 = 8720962
191 + 8720771 = 8720962
233 + 8720729 = 8720962
269 + 8720693 = 8720962
281 + 8720681 = 8720962
431 + 8720531 = 8720962
449 + 8720513 = 8720962

Showing the first eight; more decompositions exist.
