Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525092, here are decompositions:

61 + 31525031 = 31525092
101 + 31524991 = 31525092
103 + 31524989 = 31525092
199 + 31524893 = 31525092
229 + 31524863 = 31525092
283 + 31524809 = 31525092
419 + 31524673 = 31525092
449 + 31524643 = 31525092

Showing the first eight; more decompositions exist.
