Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472712, here are decompositions:

13 + 31472699 = 31472712
43 + 31472669 = 31472712
79 + 31472633 = 31472712
101 + 31472611 = 31472712
211 + 31472501 = 31472712
223 + 31472489 = 31472712
233 + 31472479 = 31472712
263 + 31472449 = 31472712

Showing the first eight; more decompositions exist.
