Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532386, here are decompositions:

47 + 31532339 = 31532386
107 + 31532279 = 31532386
167 + 31532219 = 31532386
269 + 31532117 = 31532386
383 + 31532003 = 31532386
419 + 31531967 = 31532386
503 + 31531883 = 31532386
569 + 31531817 = 31532386

Showing the first eight; more decompositions exist.
