Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465474, here are decompositions:

23 + 31465451 = 31465474
83 + 31465391 = 31465474
251 + 31465223 = 31465474
281 + 31465193 = 31465474
647 + 31464827 = 31465474
653 + 31464821 = 31465474
743 + 31464731 = 31465474
773 + 31464701 = 31465474

Showing the first eight; more decompositions exist.
