Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535752, here are decompositions:

5 + 31535747 = 31535752
11 + 31535741 = 31535752
71 + 31535681 = 31535752
113 + 31535639 = 31535752
431 + 31535321 = 31535752
569 + 31535183 = 31535752
719 + 31535033 = 31535752
839 + 31534913 = 31535752

Showing the first eight; more decompositions exist.
