Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496546, here are decompositions:

7 + 31496539 = 31496546
97 + 31496449 = 31496546
127 + 31496419 = 31496546
157 + 31496389 = 31496546
229 + 31496317 = 31496546
283 + 31496263 = 31496546
337 + 31496209 = 31496546
373 + 31496173 = 31496546

Showing the first eight; more decompositions exist.
