Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589800, here are decompositions:

23 + 31589777 = 31589800
29 + 31589771 = 31589800
41 + 31589759 = 31589800
89 + 31589711 = 31589800
107 + 31589693 = 31589800
167 + 31589633 = 31589800
233 + 31589567 = 31589800
239 + 31589561 = 31589800

Showing the first eight; more decompositions exist.
