Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582616, here are decompositions:

3 + 31582613 = 31582616
7 + 31582609 = 31582616
103 + 31582513 = 31582616
127 + 31582489 = 31582616
199 + 31582417 = 31582616
283 + 31582333 = 31582616
349 + 31582267 = 31582616
367 + 31582249 = 31582616

Showing the first eight; more decompositions exist.
