Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534936, here are decompositions:

23 + 31534913 = 31534936
137 + 31534799 = 31534936
149 + 31534787 = 31534936
179 + 31534757 = 31534936
197 + 31534739 = 31534936
227 + 31534709 = 31534936
347 + 31534589 = 31534936
383 + 31534553 = 31534936

Showing the first eight; more decompositions exist.
