Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496986, here are decompositions:

23 + 31496963 = 31496986
29 + 31496957 = 31496986
113 + 31496873 = 31496986
167 + 31496819 = 31496986
293 + 31496693 = 31496986
317 + 31496669 = 31496986
419 + 31496567 = 31496986
449 + 31496537 = 31496986

Showing the first eight; more decompositions exist.
