Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535758, here are decompositions:

5 + 31535753 = 31535758
11 + 31535747 = 31535758
17 + 31535741 = 31535758
41 + 31535717 = 31535758
101 + 31535657 = 31535758
167 + 31535591 = 31535758
347 + 31535411 = 31535758
431 + 31535327 = 31535758

Showing the first eight; more decompositions exist.
