Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719580, here are decompositions:

3 + 8719577 = 8719580
7 + 8719573 = 8719580
13 + 8719567 = 8719580
31 + 8719549 = 8719580
61 + 8719519 = 8719580
97 + 8719483 = 8719580
139 + 8719441 = 8719580
277 + 8719303 = 8719580

Showing the first eight; more decompositions exist.
