Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535824, here are decompositions:

3 + 31535821 = 31535824
71 + 31535753 = 31535824
83 + 31535741 = 31535824
107 + 31535717 = 31535824
167 + 31535657 = 31535824
191 + 31535633 = 31535824
233 + 31535591 = 31535824
401 + 31535423 = 31535824

Showing the first eight; more decompositions exist.
