Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472664, here are decompositions:

31 + 31472633 = 31472664
53 + 31472611 = 31472664
73 + 31472591 = 31472664
127 + 31472537 = 31472664
163 + 31472501 = 31472664
227 + 31472437 = 31472664
313 + 31472351 = 31472664
373 + 31472291 = 31472664

Showing the first eight; more decompositions exist.
