Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589058, here are decompositions:

31 + 31589027 = 31589058
41 + 31589017 = 31589058
47 + 31589011 = 31589058
79 + 31588979 = 31589058
101 + 31588957 = 31589058
107 + 31588951 = 31589058
131 + 31588927 = 31589058
211 + 31588847 = 31589058

Showing the first eight; more decompositions exist.
