Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480914, here are decompositions:

13 + 31480901 = 31480914
41 + 31480873 = 31480914
53 + 31480861 = 31480914
151 + 31480763 = 31480914
181 + 31480733 = 31480914
233 + 31480681 = 31480914
293 + 31480621 = 31480914
523 + 31480391 = 31480914

Showing the first eight; more decompositions exist.
