Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464980, here are decompositions:

7 + 31464973 = 31464980
13 + 31464967 = 31464980
97 + 31464883 = 31464980
193 + 31464787 = 31464980
199 + 31464781 = 31464980
223 + 31464757 = 31464980
271 + 31464709 = 31464980
331 + 31464649 = 31464980

Showing the first eight; more decompositions exist.
