Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589248, here are decompositions:

149 + 31589099 = 31589248
179 + 31589069 = 31589248
191 + 31589057 = 31589248
269 + 31588979 = 31589248
401 + 31588847 = 31589248
569 + 31588679 = 31589248
617 + 31588631 = 31589248
641 + 31588607 = 31589248

Showing the first eight; more decompositions exist.
