Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650520, here are decompositions:

3 + 8650517 = 8650520
61 + 8650459 = 8650520
97 + 8650423 = 8650520
199 + 8650321 = 8650520
211 + 8650309 = 8650520
331 + 8650189 = 8650520
367 + 8650153 = 8650520
379 + 8650141 = 8650520

Showing the first eight; more decompositions exist.
