Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532788, here are decompositions:

11 + 31532777 = 31532788
101 + 31532687 = 31532788
149 + 31532639 = 31532788
191 + 31532597 = 31532788
281 + 31532507 = 31532788
311 + 31532477 = 31532788
359 + 31532429 = 31532788
449 + 31532339 = 31532788

Showing the first eight; more decompositions exist.
