Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472706, here are decompositions:

7 + 31472699 = 31472706
37 + 31472669 = 31472706
43 + 31472663 = 31472706
73 + 31472633 = 31472706
227 + 31472479 = 31472706
257 + 31472449 = 31472706
269 + 31472437 = 31472706
347 + 31472359 = 31472706

Showing the first eight; more decompositions exist.
