Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582608, here are decompositions:

7 + 31582601 = 31582608
19 + 31582589 = 31582608
61 + 31582547 = 31582608
137 + 31582471 = 31582608
191 + 31582417 = 31582608
199 + 31582409 = 31582608
271 + 31582337 = 31582608
359 + 31582249 = 31582608

Showing the first eight; more decompositions exist.
