Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615580, here are decompositions:

13 + 8615567 = 8615580
37 + 8615543 = 8615580
41 + 8615539 = 8615580
53 + 8615527 = 8615580
67 + 8615513 = 8615580
73 + 8615507 = 8615580
89 + 8615491 = 8615580
101 + 8615479 = 8615580

Showing the first eight; more decompositions exist.
