Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564344, here are decompositions:

11 + 31564333 = 31564344
13 + 31564331 = 31564344
17 + 31564327 = 31564344
23 + 31564321 = 31564344
73 + 31564271 = 31564344
83 + 31564261 = 31564344
101 + 31564243 = 31564344
103 + 31564241 = 31564344

Showing the first eight; more decompositions exist.
