Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446584, here are decompositions:

31 + 31446553 = 31446584
157 + 31446427 = 31446584
223 + 31446361 = 31446584
331 + 31446253 = 31446584
373 + 31446211 = 31446584
487 + 31446097 = 31446584
523 + 31446061 = 31446584
601 + 31445983 = 31446584

Showing the first eight; more decompositions exist.
