Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532496, here are decompositions:

7 + 31532489 = 31532496
19 + 31532477 = 31532496
59 + 31532437 = 31532496
67 + 31532429 = 31532496
157 + 31532339 = 31532496
167 + 31532329 = 31532496
173 + 31532323 = 31532496
227 + 31532269 = 31532496

Showing the first eight; more decompositions exist.
