Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616546, here are decompositions:

7 + 31616539 = 31616546
37 + 31616509 = 31616546
67 + 31616479 = 31616546
127 + 31616419 = 31616546
373 + 31616173 = 31616546
397 + 31616149 = 31616546
433 + 31616113 = 31616546
487 + 31616059 = 31616546

Showing the first eight; more decompositions exist.
