Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525496, here are decompositions:

7 + 31525489 = 31525496
19 + 31525477 = 31525496
229 + 31525267 = 31525496
283 + 31525213 = 31525496
313 + 31525183 = 31525496
733 + 31524763 = 31525496
823 + 31524673 = 31525496
853 + 31524643 = 31525496

Showing the first eight; more decompositions exist.
