Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535066, here are decompositions:

7 + 31535059 = 31535066
67 + 31534999 = 31535066
193 + 31534873 = 31535066
313 + 31534753 = 31535066
337 + 31534729 = 31535066
397 + 31534669 = 31535066
523 + 31534543 = 31535066
643 + 31534423 = 31535066

Showing the first eight; more decompositions exist.
