Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179878, here are decompositions:

29 + 179849 = 179878
59 + 179819 = 179878
71 + 179807 = 179878
191 + 179687 = 179878
227 + 179651 = 179878
359 + 179519 = 179878
449 + 179429 = 179878
467 + 179411 = 179878

Showing the first eight; more decompositions exist.
