Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180874, here are decompositions:

3 + 180871 = 180874
101 + 180773 = 180874
173 + 180701 = 180874
227 + 180647 = 180874
251 + 180623 = 180874
257 + 180617 = 180874
311 + 180563 = 180874
383 + 180491 = 180874

Showing the first eight; more decompositions exist.
