Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535038, here are decompositions:

5 + 31535033 = 31535038
167 + 31534871 = 31535038
239 + 31534799 = 31535038
251 + 31534787 = 31535038
281 + 31534757 = 31535038
347 + 31534691 = 31535038
401 + 31534637 = 31535038
449 + 31534589 = 31535038

Showing the first eight; more decompositions exist.
