Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589426, here are decompositions:

3 + 31589423 = 31589426
19 + 31589407 = 31589426
67 + 31589359 = 31589426
73 + 31589353 = 31589426
97 + 31589329 = 31589426
109 + 31589317 = 31589426
139 + 31589287 = 31589426
229 + 31589197 = 31589426

Showing the first eight; more decompositions exist.
