Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588322, here are decompositions:

19 + 31588303 = 31588322
151 + 31588171 = 31588322
193 + 31588129 = 31588322
373 + 31587949 = 31588322
379 + 31587943 = 31588322
463 + 31587859 = 31588322
523 + 31587799 = 31588322
541 + 31587781 = 31588322

Showing the first eight; more decompositions exist.
