Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464474, here are decompositions:

11 + 31464463 = 31464474
23 + 31464451 = 31464474
31 + 31464443 = 31464474
47 + 31464427 = 31464474
53 + 31464421 = 31464474
73 + 31464401 = 31464474
193 + 31464281 = 31464474
241 + 31464233 = 31464474

Showing the first eight; more decompositions exist.
