Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527996, here are decompositions:

29 + 31527967 = 31527996
83 + 31527913 = 31527996
109 + 31527887 = 31527996
167 + 31527829 = 31527996
179 + 31527817 = 31527996
293 + 31527703 = 31527996
307 + 31527689 = 31527996
337 + 31527659 = 31527996

Showing the first eight; more decompositions exist.
