Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564332, here are decompositions:

5 + 31564327 = 31564332
11 + 31564321 = 31564332
61 + 31564271 = 31564332
71 + 31564261 = 31564332
83 + 31564249 = 31564332
89 + 31564243 = 31564332
103 + 31564229 = 31564332
193 + 31564139 = 31564332

Showing the first eight; more decompositions exist.
