Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456734, here are decompositions:

7 + 31456727 = 31456734
13 + 31456721 = 31456734
31 + 31456703 = 31456734
83 + 31456651 = 31456734
137 + 31456597 = 31456734
233 + 31456501 = 31456734
293 + 31456441 = 31456734
373 + 31456361 = 31456734

Showing the first eight; more decompositions exist.
