Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456708, here are decompositions:

5 + 31456703 = 31456708
29 + 31456679 = 31456708
191 + 31456517 = 31456708
347 + 31456361 = 31456708
389 + 31456319 = 31456708
431 + 31456277 = 31456708
449 + 31456259 = 31456708
461 + 31456247 = 31456708

Showing the first eight; more decompositions exist.
