Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588934, here are decompositions:

7 + 31588927 = 31588934
37 + 31588897 = 31588934
127 + 31588807 = 31588934
241 + 31588693 = 31588934
277 + 31588657 = 31588934
331 + 31588603 = 31588934
373 + 31588561 = 31588934
463 + 31588471 = 31588934

Showing the first eight; more decompositions exist.
