Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589554, here are decompositions:

41 + 31589513 = 31589554
71 + 31589483 = 31589554
131 + 31589423 = 31589554
233 + 31589321 = 31589554
251 + 31589303 = 31589554
257 + 31589297 = 31589554
263 + 31589291 = 31589554
467 + 31589087 = 31589554

Showing the first eight; more decompositions exist.
