Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588664, here are decompositions:

7 + 31588657 = 31588664
61 + 31588603 = 31588664
103 + 31588561 = 31588664
181 + 31588483 = 31588664
193 + 31588471 = 31588664
223 + 31588441 = 31588664
307 + 31588357 = 31588664
313 + 31588351 = 31588664

Showing the first eight; more decompositions exist.
