Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618580, here are decompositions:

13 + 8618567 = 8618580
23 + 8618557 = 8618580
79 + 8618501 = 8618580
97 + 8618483 = 8618580
101 + 8618479 = 8618580
137 + 8618443 = 8618580
151 + 8618429 = 8618580
167 + 8618413 = 8618580

Showing the first eight; more decompositions exist.
