Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472992, here are decompositions:

29 + 31472963 = 31472992
101 + 31472891 = 31472992
113 + 31472879 = 31472992
179 + 31472813 = 31472992
269 + 31472723 = 31472992
293 + 31472699 = 31472992
359 + 31472633 = 31472992
401 + 31472591 = 31472992

Showing the first eight; more decompositions exist.
