Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506014, here are decompositions:

31 + 31505983 = 31506014
193 + 31505821 = 31506014
277 + 31505737 = 31506014
283 + 31505731 = 31506014
313 + 31505701 = 31506014
487 + 31505527 = 31506014
541 + 31505473 = 31506014
571 + 31505443 = 31506014

Showing the first eight; more decompositions exist.
