Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535012, here are decompositions:

13 + 31534999 = 31535012
31 + 31534981 = 31535012
139 + 31534873 = 31535012
181 + 31534831 = 31535012
193 + 31534819 = 31535012
211 + 31534801 = 31535012
283 + 31534729 = 31535012
571 + 31534441 = 31535012

Showing the first eight; more decompositions exist.
