Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463474, here are decompositions:

67 + 31463407 = 31463474
157 + 31463317 = 31463474
193 + 31463281 = 31463474
271 + 31463203 = 31463474
277 + 31463197 = 31463474
307 + 31463167 = 31463474
313 + 31463161 = 31463474
337 + 31463137 = 31463474

Showing the first eight; more decompositions exist.
