Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589404, here are decompositions:

3 + 31589401 = 31589404
71 + 31589333 = 31589404
83 + 31589321 = 31589404
101 + 31589303 = 31589404
107 + 31589297 = 31589404
113 + 31589291 = 31589404
317 + 31589087 = 31589404
347 + 31589057 = 31589404

Showing the first eight; more decompositions exist.
