Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535336, here are decompositions:

73 + 31535263 = 31535336
103 + 31535233 = 31535336
109 + 31535227 = 31535336
163 + 31535173 = 31535336
193 + 31535143 = 31535336
223 + 31535113 = 31535336
229 + 31535107 = 31535336
277 + 31535059 = 31535336

Showing the first eight; more decompositions exist.
