Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720562, here are decompositions:

5 + 8720557 = 8720562
29 + 8720533 = 8720562
31 + 8720531 = 8720562
73 + 8720489 = 8720562
79 + 8720483 = 8720562
83 + 8720479 = 8720562
131 + 8720431 = 8720562
173 + 8720389 = 8720562

Showing the first eight; more decompositions exist.
