Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616282, here are decompositions:

31 + 31616251 = 31616282
109 + 31616173 = 31616282
223 + 31616059 = 31616282
241 + 31616041 = 31616282
283 + 31615999 = 31616282
331 + 31615951 = 31616282
433 + 31615849 = 31616282
499 + 31615783 = 31616282

Showing the first eight; more decompositions exist.
