Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178012, here are decompositions:

11 + 178001 = 178012
59 + 177953 = 178012
83 + 177929 = 178012
173 + 177839 = 178012
251 + 177761 = 178012
269 + 177743 = 178012
389 + 177623 = 178012
479 + 177533 = 178012

Showing the first eight; more decompositions exist.
