Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464950, here are decompositions:

3 + 31464947 = 31464950
67 + 31464883 = 31464950
163 + 31464787 = 31464950
193 + 31464757 = 31464950
241 + 31464709 = 31464950
331 + 31464619 = 31464950
373 + 31464577 = 31464950
379 + 31464571 = 31464950

Showing the first eight; more decompositions exist.
