Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464612, here are decompositions:

31 + 31464581 = 31464612
41 + 31464571 = 31464612
103 + 31464509 = 31464612
131 + 31464481 = 31464612
149 + 31464463 = 31464612
173 + 31464439 = 31464612
191 + 31464421 = 31464612
211 + 31464401 = 31464612

Showing the first eight; more decompositions exist.
