Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588958, here are decompositions:

7 + 31588951 = 31588958
31 + 31588927 = 31588958
61 + 31588897 = 31588958
151 + 31588807 = 31588958
397 + 31588561 = 31588958
487 + 31588471 = 31588958
601 + 31588357 = 31588958
607 + 31588351 = 31588958

Showing the first eight; more decompositions exist.
