Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589748, here are decompositions:

11 + 31589737 = 31589748
17 + 31589731 = 31589748
37 + 31589711 = 31589748
41 + 31589707 = 31589748
89 + 31589659 = 31589748
137 + 31589611 = 31589748
181 + 31589567 = 31589748
347 + 31589401 = 31589748

Showing the first eight; more decompositions exist.
