Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564362, here are decompositions:

29 + 31564333 = 31564362
31 + 31564331 = 31564362
41 + 31564321 = 31564362
101 + 31564261 = 31564362
113 + 31564249 = 31564362
191 + 31564171 = 31564362
199 + 31564163 = 31564362
223 + 31564139 = 31564362

Showing the first eight; more decompositions exist.
