Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579796, here are decompositions:

163 + 31579633 = 31579796
229 + 31579567 = 31579796
277 + 31579519 = 31579796
349 + 31579447 = 31579796
397 + 31579399 = 31579796
439 + 31579357 = 31579796
709 + 31579087 = 31579796
757 + 31579039 = 31579796

Showing the first eight; more decompositions exist.
