Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589158, here are decompositions:

59 + 31589099 = 31589158
71 + 31589087 = 31589158
89 + 31589069 = 31589158
101 + 31589057 = 31589158
131 + 31589027 = 31589158
179 + 31588979 = 31589158
311 + 31588847 = 31589158
449 + 31588709 = 31589158

Showing the first eight; more decompositions exist.
