Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532558, here are decompositions:

7 + 31532551 = 31532558
19 + 31532539 = 31532558
37 + 31532521 = 31532558
61 + 31532497 = 31532558
157 + 31532401 = 31532558
229 + 31532329 = 31532558
331 + 31532227 = 31532558
349 + 31532209 = 31532558

Showing the first eight; more decompositions exist.
