Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535186, here are decompositions:

3 + 31535183 = 31535186
13 + 31535173 = 31535186
43 + 31535143 = 31535186
73 + 31535113 = 31535186
79 + 31535107 = 31535186
103 + 31535083 = 31535186
127 + 31535059 = 31535186
307 + 31534879 = 31535186

Showing the first eight; more decompositions exist.
