Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589048, here are decompositions:

31 + 31589017 = 31589048
37 + 31589011 = 31589048
97 + 31588951 = 31589048
151 + 31588897 = 31589048
241 + 31588807 = 31589048
349 + 31588699 = 31589048
487 + 31588561 = 31589048
577 + 31588471 = 31589048

Showing the first eight; more decompositions exist.
