Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464900, here are decompositions:

17 + 31464883 = 31464900
73 + 31464827 = 31464900
79 + 31464821 = 31464900
113 + 31464787 = 31464900
191 + 31464709 = 31464900
199 + 31464701 = 31464900
251 + 31464649 = 31464900
281 + 31464619 = 31464900

Showing the first eight; more decompositions exist.
