Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589236, here are decompositions:

53 + 31589183 = 31589236
137 + 31589099 = 31589236
149 + 31589087 = 31589236
167 + 31589069 = 31589236
179 + 31589057 = 31589236
257 + 31588979 = 31589236
293 + 31588943 = 31589236
389 + 31588847 = 31589236

Showing the first eight; more decompositions exist.
