Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590634, here are decompositions:

3 + 31590631 = 31590634
17 + 31590617 = 31590634
41 + 31590593 = 31590634
83 + 31590551 = 31590634
167 + 31590467 = 31590634
191 + 31590443 = 31590634
233 + 31590401 = 31590634
263 + 31590371 = 31590634

Showing the first eight; more decompositions exist.
