Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535738, here are decompositions:

67 + 31535671 = 31535738
271 + 31535467 = 31535738
397 + 31535341 = 31535738
607 + 31535131 = 31535738
631 + 31535107 = 31535738
727 + 31535011 = 31535738
739 + 31534999 = 31535738
757 + 31534981 = 31535738

Showing the first eight; more decompositions exist.
