Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601520, here are decompositions:

17 + 8601503 = 8601520
29 + 8601491 = 8601520
71 + 8601449 = 8601520
131 + 8601389 = 8601520
227 + 8601293 = 8601520
311 + 8601209 = 8601520
419 + 8601101 = 8601520
443 + 8601077 = 8601520

Showing the first eight; more decompositions exist.
