Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523266, here are decompositions:

23 + 31523243 = 31523266
29 + 31523237 = 31523266
59 + 31523207 = 31523266
167 + 31523099 = 31523266
239 + 31523027 = 31523266
263 + 31523003 = 31523266
419 + 31522847 = 31523266
443 + 31522823 = 31523266

Showing the first eight; more decompositions exist.
