Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523236, here are decompositions:

5 + 31523231 = 31523236
29 + 31523207 = 31523236
137 + 31523099 = 31523236
233 + 31523003 = 31523236
257 + 31522979 = 31523236
347 + 31522889 = 31523236
389 + 31522847 = 31523236
653 + 31522583 = 31523236

Showing the first eight; more decompositions exist.
