Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544532, here are decompositions:

23 + 31544509 = 31544532
139 + 31544393 = 31544532
251 + 31544281 = 31544532
311 + 31544221 = 31544532
353 + 31544179 = 31544532
379 + 31544153 = 31544532
401 + 31544131 = 31544532
433 + 31544099 = 31544532

Showing the first eight; more decompositions exist.
