Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635580, here are decompositions:

13 + 8635567 = 8635580
67 + 8635513 = 8635580
103 + 8635477 = 8635580
139 + 8635441 = 8635580
157 + 8635423 = 8635580
199 + 8635381 = 8635580
229 + 8635351 = 8635580
307 + 8635273 = 8635580

Showing the first eight; more decompositions exist.
