Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532266, here are decompositions:

5 + 31532261 = 31532266
47 + 31532219 = 31532266
149 + 31532117 = 31532266
263 + 31532003 = 31532266
383 + 31531883 = 31532266
449 + 31531817 = 31532266
587 + 31531679 = 31532266
599 + 31531667 = 31532266

Showing the first eight; more decompositions exist.
