Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464020, here are decompositions:

19 + 31464001 = 31464020
61 + 31463959 = 31464020
79 + 31463941 = 31464020
109 + 31463911 = 31464020
127 + 31463893 = 31464020
163 + 31463857 = 31464020
193 + 31463827 = 31464020
223 + 31463797 = 31464020

Showing the first eight; more decompositions exist.
