Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564350, here are decompositions:

17 + 31564333 = 31564350
19 + 31564331 = 31564350
23 + 31564327 = 31564350
29 + 31564321 = 31564350
79 + 31564271 = 31564350
89 + 31564261 = 31564350
101 + 31564249 = 31564350
107 + 31564243 = 31564350

Showing the first eight; more decompositions exist.
