Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480996, here are decompositions:

23 + 31480973 = 31480996
47 + 31480949 = 31480996
83 + 31480913 = 31480996
167 + 31480829 = 31480996
227 + 31480769 = 31480996
233 + 31480763 = 31480996
263 + 31480733 = 31480996
347 + 31480649 = 31480996

Showing the first eight; more decompositions exist.
