Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458276, here are decompositions:

37 + 31458239 = 31458276
79 + 31458197 = 31458276
89 + 31458187 = 31458276
103 + 31458173 = 31458276
107 + 31458169 = 31458276
163 + 31458113 = 31458276
193 + 31458083 = 31458276
263 + 31458013 = 31458276

Showing the first eight; more decompositions exist.
