Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566236, here are decompositions:

67 + 31566169 = 31566236
157 + 31566079 = 31566236
193 + 31566043 = 31566236
223 + 31566013 = 31566236
283 + 31565953 = 31566236
307 + 31565929 = 31566236
349 + 31565887 = 31566236
367 + 31565869 = 31566236

Showing the first eight; more decompositions exist.
