Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525504, here are decompositions:

5 + 31525499 = 31525504
83 + 31525421 = 31525504
107 + 31525397 = 31525504
137 + 31525367 = 31525504
173 + 31525331 = 31525504
293 + 31525211 = 31525504
383 + 31525121 = 31525504
401 + 31525103 = 31525504

Showing the first eight; more decompositions exist.
