Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456594, here are decompositions:

5 + 31456589 = 31456594
47 + 31456547 = 31456594
107 + 31456487 = 31456594
233 + 31456361 = 31456594
263 + 31456331 = 31456594
317 + 31456277 = 31456594
347 + 31456247 = 31456594
353 + 31456241 = 31456594

Showing the first eight; more decompositions exist.
