Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663580, here are decompositions:

43 + 8663537 = 8663580
59 + 8663521 = 8663580
61 + 8663519 = 8663580
71 + 8663509 = 8663580
73 + 8663507 = 8663580
83 + 8663497 = 8663580
109 + 8663471 = 8663580
113 + 8663467 = 8663580

Showing the first eight; more decompositions exist.
