Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525574, here are decompositions:

7 + 31525567 = 31525574
37 + 31525537 = 31525574
97 + 31525477 = 31525574
127 + 31525447 = 31525574
307 + 31525267 = 31525574
313 + 31525261 = 31525574
331 + 31525243 = 31525574
373 + 31525201 = 31525574

Showing the first eight; more decompositions exist.
