Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525528, here are decompositions:

29 + 31525499 = 31525528
107 + 31525421 = 31525528
131 + 31525397 = 31525528
149 + 31525379 = 31525528
197 + 31525331 = 31525528
239 + 31525289 = 31525528
317 + 31525211 = 31525528
401 + 31525127 = 31525528

Showing the first eight; more decompositions exist.
