Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532746, here are decompositions:

53 + 31532693 = 31532746
59 + 31532687 = 31532746
107 + 31532639 = 31532746
149 + 31532597 = 31532746
173 + 31532573 = 31532746
239 + 31532507 = 31532746
257 + 31532489 = 31532746
269 + 31532477 = 31532746

Showing the first eight; more decompositions exist.
