Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589028, here are decompositions:

11 + 31589017 = 31589028
17 + 31589011 = 31589028
71 + 31588957 = 31589028
101 + 31588927 = 31589028
131 + 31588897 = 31589028
181 + 31588847 = 31589028
349 + 31588679 = 31589028
397 + 31588631 = 31589028

Showing the first eight; more decompositions exist.
