Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589292, here are decompositions:

5 + 31589287 = 31589292
41 + 31589251 = 31589292
109 + 31589183 = 31589292
173 + 31589119 = 31589292
193 + 31589099 = 31589292
223 + 31589069 = 31589292
281 + 31589011 = 31589292
313 + 31588979 = 31589292

Showing the first eight; more decompositions exist.
