Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720588, here are decompositions:

7 + 8720581 = 8720588
31 + 8720557 = 8720588
109 + 8720479 = 8720588
157 + 8720431 = 8720588
181 + 8720407 = 8720588
199 + 8720389 = 8720588
241 + 8720347 = 8720588
271 + 8720317 = 8720588

Showing the first eight; more decompositions exist.
