Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589394, here are decompositions:

17 + 31589377 = 31589394
41 + 31589353 = 31589394
61 + 31589333 = 31589394
73 + 31589321 = 31589394
97 + 31589297 = 31589394
101 + 31589293 = 31589394
103 + 31589291 = 31589394
107 + 31589287 = 31589394

Showing the first eight; more decompositions exist.
