Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566284, here are decompositions:

37 + 31566247 = 31566284
223 + 31566061 = 31566284
241 + 31566043 = 31566284
271 + 31566013 = 31566284
283 + 31566001 = 31566284
313 + 31565971 = 31566284
331 + 31565953 = 31566284
367 + 31565917 = 31566284

Showing the first eight; more decompositions exist.
