Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472914, here are decompositions:

23 + 31472891 = 31472914
47 + 31472867 = 31472914
101 + 31472813 = 31472914
107 + 31472807 = 31472914
191 + 31472723 = 31472914
251 + 31472663 = 31472914
281 + 31472633 = 31472914
563 + 31472351 = 31472914

Showing the first eight; more decompositions exist.
