Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496286, here are decompositions:

23 + 31496263 = 31496286
67 + 31496219 = 31496286
113 + 31496173 = 31496286
163 + 31496123 = 31496286
167 + 31496119 = 31496286
229 + 31496057 = 31496286
307 + 31495979 = 31496286
337 + 31495949 = 31496286

Showing the first eight; more decompositions exist.
