Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464584, here are decompositions:

3 + 31464581 = 31464584
7 + 31464577 = 31464584
13 + 31464571 = 31464584
37 + 31464547 = 31464584
103 + 31464481 = 31464584
157 + 31464427 = 31464584
163 + 31464421 = 31464584
313 + 31464271 = 31464584

Showing the first eight; more decompositions exist.
