Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525002, here are decompositions:

11 + 31524991 = 31525002
13 + 31524989 = 31525002
109 + 31524893 = 31525002
139 + 31524863 = 31525002
163 + 31524839 = 31525002
193 + 31524809 = 31525002
211 + 31524791 = 31525002
239 + 31524763 = 31525002

Showing the first eight; more decompositions exist.
