Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456606, here are decompositions:

17 + 31456589 = 31456606
59 + 31456547 = 31456606
89 + 31456517 = 31456606
227 + 31456379 = 31456606
347 + 31456259 = 31456606
359 + 31456247 = 31456606
443 + 31456163 = 31456606
593 + 31456013 = 31456606

Showing the first eight; more decompositions exist.
