Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589262, here are decompositions:

11 + 31589251 = 31589262
79 + 31589183 = 31589262
163 + 31589099 = 31589262
193 + 31589069 = 31589262
251 + 31589011 = 31589262
269 + 31588993 = 31589262
283 + 31588979 = 31589262
311 + 31588951 = 31589262

Showing the first eight; more decompositions exist.
