Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456766, here are decompositions:

97 + 31456669 = 31456766
127 + 31456639 = 31456766
337 + 31456429 = 31456766
487 + 31456279 = 31456766
547 + 31456219 = 31456766
643 + 31456123 = 31456766
673 + 31456093 = 31456766
877 + 31455889 = 31456766

Showing the first eight; more decompositions exist.
