Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707720, here are decompositions:

23 + 8707697 = 8707720
59 + 8707661 = 8707720
71 + 8707649 = 8707720
89 + 8707631 = 8707720
113 + 8707607 = 8707720
431 + 8707289 = 8707720
443 + 8707277 = 8707720
479 + 8707241 = 8707720

Showing the first eight; more decompositions exist.
