Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464566, here are decompositions:

19 + 31464547 = 31464566
73 + 31464493 = 31464566
103 + 31464463 = 31464566
127 + 31464439 = 31464566
139 + 31464427 = 31464566
157 + 31464409 = 31464566
373 + 31464193 = 31464566
379 + 31464187 = 31464566

Showing the first eight; more decompositions exist.
