Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496454, here are decompositions:

5 + 31496449 = 31496454
13 + 31496441 = 31496454
37 + 31496417 = 31496454
83 + 31496371 = 31496454
137 + 31496317 = 31496454
191 + 31496263 = 31496454
193 + 31496261 = 31496454
233 + 31496221 = 31496454

Showing the first eight; more decompositions exist.
