Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525558, here are decompositions:

5 + 31525553 = 31525558
59 + 31525499 = 31525558
137 + 31525421 = 31525558
179 + 31525379 = 31525558
191 + 31525367 = 31525558
227 + 31525331 = 31525558
269 + 31525289 = 31525558
347 + 31525211 = 31525558

Showing the first eight; more decompositions exist.
