Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472676, here are decompositions:

7 + 31472669 = 31472676
13 + 31472663 = 31472676
43 + 31472633 = 31472676
89 + 31472587 = 31472676
139 + 31472537 = 31472676
197 + 31472479 = 31472676
227 + 31472449 = 31472676
239 + 31472437 = 31472676

Showing the first eight; more decompositions exist.
