Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589128, here are decompositions:

29 + 31589099 = 31589128
41 + 31589087 = 31589128
59 + 31589069 = 31589128
71 + 31589057 = 31589128
101 + 31589027 = 31589128
149 + 31588979 = 31589128
281 + 31588847 = 31589128
419 + 31588709 = 31589128

Showing the first eight; more decompositions exist.
