Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472674, here are decompositions:

5 + 31472669 = 31472674
11 + 31472663 = 31472674
41 + 31472633 = 31472674
83 + 31472591 = 31472674
137 + 31472537 = 31472674
173 + 31472501 = 31472674
383 + 31472291 = 31472674
491 + 31472183 = 31472674

Showing the first eight; more decompositions exist.
