Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601706, here are decompositions:

7 + 31601699 = 31601706
137 + 31601569 = 31601706
139 + 31601567 = 31601706
167 + 31601539 = 31601706
179 + 31601527 = 31601706
193 + 31601513 = 31601706
197 + 31601509 = 31601706
233 + 31601473 = 31601706

Showing the first eight; more decompositions exist.
