Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532282, here are decompositions:

3 + 31532279 = 31532282
13 + 31532269 = 31532282
73 + 31532209 = 31532282
79 + 31532203 = 31532282
193 + 31532089 = 31532282
211 + 31532071 = 31532282
373 + 31531909 = 31532282
643 + 31531639 = 31532282

Showing the first eight; more decompositions exist.
