Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535848, here are decompositions:

17 + 31535831 = 31535848
101 + 31535747 = 31535848
107 + 31535741 = 31535848
131 + 31535717 = 31535848
167 + 31535681 = 31535848
191 + 31535657 = 31535848
257 + 31535591 = 31535848
419 + 31535429 = 31535848

Showing the first eight; more decompositions exist.
