Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457346, here are decompositions:

5 + 31457341 = 31457346
17 + 31457329 = 31457346
43 + 31457303 = 31457346
59 + 31457287 = 31457346
79 + 31457267 = 31457346
197 + 31457149 = 31457346
227 + 31457119 = 31457346
307 + 31457039 = 31457346

Showing the first eight; more decompositions exist.
