Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456674, here are decompositions:

5 + 31456669 = 31456674
23 + 31456651 = 31456674
127 + 31456547 = 31456674
157 + 31456517 = 31456674
173 + 31456501 = 31456674
233 + 31456441 = 31456674
313 + 31456361 = 31456674
383 + 31456291 = 31456674

Showing the first eight; more decompositions exist.
