Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589418, here are decompositions:

11 + 31589407 = 31589418
17 + 31589401 = 31589418
41 + 31589377 = 31589418
59 + 31589359 = 31589418
79 + 31589339 = 31589418
89 + 31589329 = 31589418
97 + 31589321 = 31589418
101 + 31589317 = 31589418

Showing the first eight; more decompositions exist.
