Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180608, here are decompositions:

61 + 180547 = 180608
67 + 180541 = 180608
97 + 180511 = 180608
229 + 180379 = 180608
271 + 180337 = 180608
277 + 180331 = 180608
349 + 180259 = 180608
367 + 180241 = 180608

Showing the first eight; more decompositions exist.
