Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180560, here are decompositions:

13 + 180547 = 180560
19 + 180541 = 180560
97 + 180463 = 180560
181 + 180379 = 180560
199 + 180361 = 180560
223 + 180337 = 180560
229 + 180331 = 180560
271 + 180289 = 180560

Showing the first eight; more decompositions exist.
