Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589346, here are decompositions:

7 + 31589339 = 31589346
13 + 31589333 = 31589346
17 + 31589329 = 31589346
29 + 31589317 = 31589346
43 + 31589303 = 31589346
53 + 31589293 = 31589346
59 + 31589287 = 31589346
149 + 31589197 = 31589346

Showing the first eight; more decompositions exist.
