Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496606, here are decompositions:

7 + 31496599 = 31496606
13 + 31496593 = 31496606
19 + 31496587 = 31496606
67 + 31496539 = 31496606
157 + 31496449 = 31496606
277 + 31496329 = 31496606
313 + 31496293 = 31496606
397 + 31496209 = 31496606

Showing the first eight; more decompositions exist.
