Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680620, here are decompositions:

7 + 8680613 = 8680620
19 + 8680601 = 8680620
37 + 8680583 = 8680620
61 + 8680559 = 8680620
107 + 8680513 = 8680620
139 + 8680481 = 8680620
149 + 8680471 = 8680620
181 + 8680439 = 8680620

Showing the first eight; more decompositions exist.
