Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564532, here are decompositions:

31 + 31564501 = 31564532
73 + 31564459 = 31564532
199 + 31564333 = 31564532
211 + 31564321 = 31564532
271 + 31564261 = 31564532
283 + 31564249 = 31564532
523 + 31564009 = 31564532
661 + 31563871 = 31564532

Showing the first eight; more decompositions exist.
