Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525550, here are decompositions:

13 + 31525537 = 31525550
61 + 31525489 = 31525550
73 + 31525477 = 31525550
103 + 31525447 = 31525550
271 + 31525279 = 31525550
283 + 31525267 = 31525550
307 + 31525243 = 31525550
337 + 31525213 = 31525550

Showing the first eight; more decompositions exist.
