Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547452, here are decompositions:

3 + 31547449 = 31547452
11 + 31547441 = 31547452
113 + 31547339 = 31547452
149 + 31547303 = 31547452
191 + 31547261 = 31547452
359 + 31547093 = 31547452
389 + 31547063 = 31547452
449 + 31547003 = 31547452

Showing the first eight; more decompositions exist.
