Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588064, here are decompositions:

3 + 31588061 = 31588064
61 + 31588003 = 31588064
103 + 31587961 = 31588064
271 + 31587793 = 31588064
283 + 31587781 = 31588064
367 + 31587697 = 31588064
631 + 31587433 = 31588064
643 + 31587421 = 31588064

Showing the first eight; more decompositions exist.
