Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456934, here are decompositions:

7 + 31456927 = 31456934
31 + 31456903 = 31456934
43 + 31456891 = 31456934
193 + 31456741 = 31456934
283 + 31456651 = 31456934
337 + 31456597 = 31456934
433 + 31456501 = 31456934
643 + 31456291 = 31456934

Showing the first eight; more decompositions exist.
