Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523206, here are decompositions:

5 + 31523201 = 31523206
107 + 31523099 = 31523206
179 + 31523027 = 31523206
227 + 31522979 = 31523206
269 + 31522937 = 31523206
317 + 31522889 = 31523206
359 + 31522847 = 31523206
383 + 31522823 = 31523206

Showing the first eight; more decompositions exist.
