Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460996, here are decompositions:

19 + 31460977 = 31460996
67 + 31460929 = 31460996
79 + 31460917 = 31460996
157 + 31460839 = 31460996
163 + 31460833 = 31460996
349 + 31460647 = 31460996
487 + 31460509 = 31460996
499 + 31460497 = 31460996

Showing the first eight; more decompositions exist.
