Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567462, here are decompositions:

11 + 31567451 = 31567462
149 + 31567313 = 31567462
191 + 31567271 = 31567462
419 + 31567043 = 31567462
599 + 31566863 = 31567462
659 + 31566803 = 31567462
863 + 31566599 = 31567462
1013 + 31566449 = 31567462

Showing the first eight; more decompositions exist.
