Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496370, here are decompositions:

41 + 31496329 = 31496370
53 + 31496317 = 31496370
107 + 31496263 = 31496370
109 + 31496261 = 31496370
149 + 31496221 = 31496370
151 + 31496219 = 31496370
197 + 31496173 = 31496370
229 + 31496141 = 31496370

Showing the first eight; more decompositions exist.
