Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589074, here are decompositions:

5 + 31589069 = 31589074
17 + 31589057 = 31589074
47 + 31589027 = 31589074
131 + 31588943 = 31589074
227 + 31588847 = 31589074
401 + 31588673 = 31589074
431 + 31588643 = 31589074
443 + 31588631 = 31589074

Showing the first eight; more decompositions exist.
