Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616848, here are decompositions:

101 + 31616747 = 31616848
269 + 31616579 = 31616848
467 + 31616381 = 31616848
479 + 31616369 = 31616848
509 + 31616339 = 31616848
521 + 31616327 = 31616848
587 + 31616261 = 31616848
617 + 31616231 = 31616848

Showing the first eight; more decompositions exist.
