Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463458, here are decompositions:

29 + 31463429 = 31463458
71 + 31463387 = 31463458
137 + 31463321 = 31463458
197 + 31463261 = 31463458
311 + 31463147 = 31463458
359 + 31463099 = 31463458
479 + 31462979 = 31463458
557 + 31462901 = 31463458

Showing the first eight; more decompositions exist.
