Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711720, here are decompositions:

13 + 8711707 = 8711720
37 + 8711683 = 8711720
67 + 8711653 = 8711720
103 + 8711617 = 8711720
151 + 8711569 = 8711720
229 + 8711491 = 8711720
337 + 8711383 = 8711720
373 + 8711347 = 8711720

Showing the first eight; more decompositions exist.
