Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535754, here are decompositions:

7 + 31535747 = 31535754
13 + 31535741 = 31535754
37 + 31535717 = 31535754
73 + 31535681 = 31535754
83 + 31535671 = 31535754
97 + 31535657 = 31535754
163 + 31535591 = 31535754
251 + 31535503 = 31535754

Showing the first eight; more decompositions exist.
