Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532626, here are decompositions:

29 + 31532597 = 31532626
53 + 31532573 = 31532626
137 + 31532489 = 31532626
149 + 31532477 = 31532626
197 + 31532429 = 31532626
347 + 31532279 = 31532626
509 + 31532117 = 31532626
563 + 31532063 = 31532626

Showing the first eight; more decompositions exist.
