Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535854, here are decompositions:

23 + 31535831 = 31535854
101 + 31535753 = 31535854
107 + 31535747 = 31535854
113 + 31535741 = 31535854
137 + 31535717 = 31535854
173 + 31535681 = 31535854
197 + 31535657 = 31535854
263 + 31535591 = 31535854

Showing the first eight; more decompositions exist.
