Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525328, here are decompositions:

61 + 31525267 = 31525328
67 + 31525261 = 31525328
127 + 31525201 = 31525328
151 + 31525177 = 31525328
337 + 31524991 = 31525328
607 + 31524721 = 31525328
787 + 31524541 = 31525328
811 + 31524517 = 31525328

Showing the first eight; more decompositions exist.
