Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470996, here are decompositions:

5 + 31470991 = 31470996
19 + 31470977 = 31470996
43 + 31470953 = 31470996
79 + 31470917 = 31470996
83 + 31470913 = 31470996
107 + 31470889 = 31470996
127 + 31470869 = 31470996
149 + 31470847 = 31470996

Showing the first eight; more decompositions exist.
