Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472464, here are decompositions:

113 + 31472351 = 31472464
173 + 31472291 = 31472464
263 + 31472201 = 31472464
281 + 31472183 = 31472464
311 + 31472153 = 31472464
461 + 31472003 = 31472464
557 + 31471907 = 31472464
563 + 31471901 = 31472464

Showing the first eight; more decompositions exist.
