Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534404, here are decompositions:

61 + 31534343 = 31534404
71 + 31534333 = 31534404
103 + 31534301 = 31534404
107 + 31534297 = 31534404
157 + 31534247 = 31534404
163 + 31534241 = 31534404
173 + 31534231 = 31534404
263 + 31534141 = 31534404

Showing the first eight; more decompositions exist.
