Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534900, here are decompositions:

29 + 31534871 = 31534900
101 + 31534799 = 31534900
113 + 31534787 = 31534900
149 + 31534751 = 31534900
191 + 31534709 = 31534900
263 + 31534637 = 31534900
269 + 31534631 = 31534900
311 + 31534589 = 31534900

Showing the first eight; more decompositions exist.
