Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566134, here are decompositions:

3 + 31566131 = 31566134
73 + 31566061 = 31566134
163 + 31565971 = 31566134
181 + 31565953 = 31566134
283 + 31565851 = 31566134
331 + 31565803 = 31566134
373 + 31565761 = 31566134
421 + 31565713 = 31566134

Showing the first eight; more decompositions exist.
