Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720654, here are decompositions:

31 + 8720623 = 8720654
37 + 8720617 = 8720654
73 + 8720581 = 8720654
97 + 8720557 = 8720654
157 + 8720497 = 8720654
223 + 8720431 = 8720654
307 + 8720347 = 8720654
337 + 8720317 = 8720654

Showing the first eight; more decompositions exist.
