Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525030, here are decompositions:

3 + 31525027 = 31525030
23 + 31525007 = 31525030
41 + 31524989 = 31525030
137 + 31524893 = 31525030
167 + 31524863 = 31525030
191 + 31524839 = 31525030
233 + 31524797 = 31525030
239 + 31524791 = 31525030

Showing the first eight; more decompositions exist.
