Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566350, here are decompositions:

3 + 31566347 = 31566350
61 + 31566289 = 31566350
103 + 31566247 = 31566350
181 + 31566169 = 31566350
199 + 31566151 = 31566350
271 + 31566079 = 31566350
307 + 31566043 = 31566350
331 + 31566019 = 31566350

Showing the first eight; more decompositions exist.
