Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472824, here are decompositions:

11 + 31472813 = 31472824
17 + 31472807 = 31472824
101 + 31472723 = 31472824
191 + 31472633 = 31472824
233 + 31472591 = 31472824
563 + 31472261 = 31472824
641 + 31472183 = 31472824
701 + 31472123 = 31472824

Showing the first eight; more decompositions exist.
