Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464830, here are decompositions:

3 + 31464827 = 31464830
43 + 31464787 = 31464830
73 + 31464757 = 31464830
181 + 31464649 = 31464830
211 + 31464619 = 31464830
283 + 31464547 = 31464830
337 + 31464493 = 31464830
349 + 31464481 = 31464830

Showing the first eight; more decompositions exist.
