Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154520, here are decompositions:

19 + 154501 = 154520
61 + 154459 = 154520
97 + 154423 = 154520
103 + 154417 = 154520
151 + 154369 = 154520
181 + 154339 = 154520
199 + 154321 = 154520
229 + 154291 = 154520

Showing the first eight; more decompositions exist.
