Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589226, here are decompositions:

29 + 31589197 = 31589226
43 + 31589183 = 31589226
59 + 31589167 = 31589226
89 + 31589137 = 31589226
107 + 31589119 = 31589226
127 + 31589099 = 31589226
139 + 31589087 = 31589226
157 + 31589069 = 31589226

Showing the first eight; more decompositions exist.
