Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180706, here are decompositions:

5 + 180701 = 180706
59 + 180647 = 180706
83 + 180623 = 180706
89 + 180617 = 180706
137 + 180569 = 180706
167 + 180539 = 180706
173 + 180533 = 180706
233 + 180473 = 180706

Showing the first eight; more decompositions exist.
