Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720746, here are decompositions:

17 + 8720729 = 8720746
53 + 8720693 = 8720746
59 + 8720687 = 8720746
149 + 8720597 = 8720746
233 + 8720513 = 8720746
257 + 8720489 = 8720746
263 + 8720483 = 8720746
269 + 8720477 = 8720746

Showing the first eight; more decompositions exist.
