Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180532, here are decompositions:

29 + 180503 = 180532
41 + 180491 = 180532
59 + 180473 = 180532
113 + 180419 = 180532
251 + 180281 = 180532
269 + 180263 = 180532
293 + 180239 = 180532
311 + 180221 = 180532

Showing the first eight; more decompositions exist.
