Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716520, here are decompositions:

31 + 8716489 = 8716520
67 + 8716453 = 8716520
73 + 8716447 = 8716520
79 + 8716441 = 8716520
139 + 8716381 = 8716520
271 + 8716249 = 8716520
277 + 8716243 = 8716520
283 + 8716237 = 8716520

Showing the first eight; more decompositions exist.
