Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534948, here are decompositions:

149 + 31534799 = 31534948
191 + 31534757 = 31534948
197 + 31534751 = 31534948
239 + 31534709 = 31534948
257 + 31534691 = 31534948
311 + 31534637 = 31534948
317 + 31534631 = 31534948
359 + 31534589 = 31534948

Showing the first eight; more decompositions exist.
