Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532662, here are decompositions:

3 + 31532659 = 31532662
23 + 31532639 = 31532662
89 + 31532573 = 31532662
173 + 31532489 = 31532662
233 + 31532429 = 31532662
383 + 31532279 = 31532662
401 + 31532261 = 31532662
443 + 31532219 = 31532662

Showing the first eight; more decompositions exist.
