Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472996, here are decompositions:

13 + 31472983 = 31472996
67 + 31472929 = 31472996
109 + 31472887 = 31472996
157 + 31472839 = 31472996
223 + 31472773 = 31472996
409 + 31472587 = 31472996
547 + 31472449 = 31472996
757 + 31472239 = 31472996

Showing the first eight; more decompositions exist.
