Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539996, here are decompositions:

29 + 31539967 = 31539996
107 + 31539889 = 31539996
139 + 31539857 = 31539996
157 + 31539839 = 31539996
179 + 31539817 = 31539996
233 + 31539763 = 31539996
239 + 31539757 = 31539996
269 + 31539727 = 31539996

Showing the first eight; more decompositions exist.
