Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579896, here are decompositions:

37 + 31579859 = 31579896
43 + 31579853 = 31579896
59 + 31579837 = 31579896
83 + 31579813 = 31579896
149 + 31579747 = 31579896
157 + 31579739 = 31579896
193 + 31579703 = 31579896
263 + 31579633 = 31579896

Showing the first eight; more decompositions exist.
