Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589410, here are decompositions:

3 + 31589407 = 31589410
71 + 31589339 = 31589410
89 + 31589321 = 31589410
107 + 31589303 = 31589410
113 + 31589297 = 31589410
227 + 31589183 = 31589410
311 + 31589099 = 31589410
353 + 31589057 = 31589410

Showing the first eight; more decompositions exist.
