Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472962, here are decompositions:

71 + 31472891 = 31472962
83 + 31472879 = 31472962
113 + 31472849 = 31472962
149 + 31472813 = 31472962
239 + 31472723 = 31472962
263 + 31472699 = 31472962
293 + 31472669 = 31472962
461 + 31472501 = 31472962

Showing the first eight; more decompositions exist.
