Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535166, here are decompositions:

23 + 31535143 = 31535166
43 + 31535123 = 31535166
53 + 31535113 = 31535166
59 + 31535107 = 31535166
83 + 31535083 = 31535166
107 + 31535059 = 31535166
109 + 31535057 = 31535166
167 + 31534999 = 31535166

Showing the first eight; more decompositions exist.
