Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720570, here are decompositions:

13 + 8720557 = 8720570
37 + 8720533 = 8720570
73 + 8720497 = 8720570
139 + 8720431 = 8720570
163 + 8720407 = 8720570
181 + 8720389 = 8720570
223 + 8720347 = 8720570
337 + 8720233 = 8720570

Showing the first eight; more decompositions exist.
