Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464210, here are decompositions:

17 + 31464193 = 31464210
23 + 31464187 = 31464210
61 + 31464149 = 31464210
67 + 31464143 = 31464210
73 + 31464137 = 31464210
131 + 31464079 = 31464210
149 + 31464061 = 31464210
163 + 31464047 = 31464210

Showing the first eight; more decompositions exist.
