Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525304, here are decompositions:

37 + 31525267 = 31525304
43 + 31525261 = 31525304
61 + 31525243 = 31525304
103 + 31525201 = 31525304
127 + 31525177 = 31525304
277 + 31525027 = 31525304
313 + 31524991 = 31525304
337 + 31524967 = 31525304

Showing the first eight; more decompositions exist.
