Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582300, here are decompositions:

59 + 31582241 = 31582300
83 + 31582217 = 31582300
107 + 31582193 = 31582300
137 + 31582163 = 31582300
179 + 31582121 = 31582300
251 + 31582049 = 31582300
257 + 31582043 = 31582300
263 + 31582037 = 31582300

Showing the first eight; more decompositions exist.
