Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525508, here are decompositions:

19 + 31525489 = 31525508
31 + 31525477 = 31525508
61 + 31525447 = 31525508
229 + 31525279 = 31525508
241 + 31525267 = 31525508
307 + 31525201 = 31525508
331 + 31525177 = 31525508
541 + 31524967 = 31525508

Showing the first eight; more decompositions exist.
