Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525274, here are decompositions:

7 + 31525267 = 31525274
13 + 31525261 = 31525274
31 + 31525243 = 31525274
61 + 31525213 = 31525274
73 + 31525201 = 31525274
97 + 31525177 = 31525274
283 + 31524991 = 31525274
307 + 31524967 = 31525274

Showing the first eight; more decompositions exist.
