Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496906, here are decompositions:

43 + 31496863 = 31496906
79 + 31496827 = 31496906
97 + 31496809 = 31496906
127 + 31496779 = 31496906
229 + 31496677 = 31496906
307 + 31496599 = 31496906
313 + 31496593 = 31496906
367 + 31496539 = 31496906

Showing the first eight; more decompositions exist.
