Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622580, here are decompositions:

3 + 8622577 = 8622580
17 + 8622563 = 8622580
59 + 8622521 = 8622580
89 + 8622491 = 8622580
107 + 8622473 = 8622580
167 + 8622413 = 8622580
227 + 8622353 = 8622580
257 + 8622323 = 8622580

Showing the first eight; more decompositions exist.
