Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464140, here are decompositions:

3 + 31464137 = 31464140
61 + 31464079 = 31464140
73 + 31464067 = 31464140
79 + 31464061 = 31464140
109 + 31464031 = 31464140
139 + 31464001 = 31464140
181 + 31463959 = 31464140
199 + 31463941 = 31464140

Showing the first eight; more decompositions exist.
