Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535032, here are decompositions:

71 + 31534961 = 31535032
233 + 31534799 = 31535032
281 + 31534751 = 31535032
293 + 31534739 = 31535032
401 + 31534631 = 31535032
443 + 31534589 = 31535032
479 + 31534553 = 31535032
761 + 31534271 = 31535032

Showing the first eight; more decompositions exist.
