Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589196, here are decompositions:

13 + 31589183 = 31589196
29 + 31589167 = 31589196
59 + 31589137 = 31589196
97 + 31589099 = 31589196
109 + 31589087 = 31589196
127 + 31589069 = 31589196
139 + 31589057 = 31589196
179 + 31589017 = 31589196

Showing the first eight; more decompositions exist.
