Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589562, here are decompositions:

23 + 31589539 = 31589562
79 + 31589483 = 31589562
89 + 31589473 = 31589562
101 + 31589461 = 31589562
139 + 31589423 = 31589562
223 + 31589339 = 31589562
229 + 31589333 = 31589562
233 + 31589329 = 31589562

Showing the first eight; more decompositions exist.
