Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456552, here are decompositions:

5 + 31456547 = 31456552
173 + 31456379 = 31456552
191 + 31456361 = 31456552
233 + 31456319 = 31456552
293 + 31456259 = 31456552
311 + 31456241 = 31456552
353 + 31456199 = 31456552
359 + 31456193 = 31456552

Showing the first eight; more decompositions exist.
