Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564498, here are decompositions:

59 + 31564439 = 31564498
107 + 31564391 = 31564498
137 + 31564361 = 31564498
167 + 31564331 = 31564498
227 + 31564271 = 31564498
257 + 31564241 = 31564498
269 + 31564229 = 31564498
359 + 31564139 = 31564498

Showing the first eight; more decompositions exist.
