Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535762, here are decompositions:

211 + 31535551 = 31535762
421 + 31535341 = 31535762
499 + 31535263 = 31535762
619 + 31535143 = 31535762
631 + 31535131 = 31535762
751 + 31535011 = 31535762
883 + 31534879 = 31535762
1009 + 31534753 = 31535762

Showing the first eight; more decompositions exist.
