Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472514, here are decompositions:

13 + 31472501 = 31472514
163 + 31472351 = 31472514
223 + 31472291 = 31472514
313 + 31472201 = 31472514
331 + 31472183 = 31472514
347 + 31472167 = 31472514
383 + 31472131 = 31472514
461 + 31472053 = 31472514

Showing the first eight; more decompositions exist.
