Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482732, here are decompositions:

23 + 31482709 = 31482732
89 + 31482643 = 31482732
101 + 31482631 = 31482732
163 + 31482569 = 31482732
173 + 31482559 = 31482732
181 + 31482551 = 31482732
223 + 31482509 = 31482732
233 + 31482499 = 31482732

Showing the first eight; more decompositions exist.
