Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589430, here are decompositions:

7 + 31589423 = 31589430
23 + 31589407 = 31589430
29 + 31589401 = 31589430
53 + 31589377 = 31589430
71 + 31589359 = 31589430
97 + 31589333 = 31589430
101 + 31589329 = 31589430
109 + 31589321 = 31589430

Showing the first eight; more decompositions exist.
