Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525324, here are decompositions:

41 + 31525283 = 31525324
113 + 31525211 = 31525324
197 + 31525127 = 31525324
293 + 31525031 = 31525324
317 + 31525007 = 31525324
431 + 31524893 = 31525324
461 + 31524863 = 31525324
557 + 31524767 = 31525324

Showing the first eight; more decompositions exist.
