Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534858, here are decompositions:

59 + 31534799 = 31534858
71 + 31534787 = 31534858
101 + 31534757 = 31534858
107 + 31534751 = 31534858
149 + 31534709 = 31534858
167 + 31534691 = 31534858
227 + 31534631 = 31534858
269 + 31534589 = 31534858

Showing the first eight; more decompositions exist.
