Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45520, here are decompositions:

17 + 45503 = 45520
23 + 45497 = 45520
29 + 45491 = 45520
107 + 45413 = 45520
131 + 45389 = 45520
179 + 45341 = 45520
191 + 45329 = 45520
227 + 45293 = 45520

Showing the first eight; more decompositions exist.
