Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525202, here are decompositions:

19 + 31525183 = 31525202
211 + 31524991 = 31525202
409 + 31524793 = 31525202
439 + 31524763 = 31525202
661 + 31524541 = 31525202
733 + 31524469 = 31525202
859 + 31524343 = 31525202
1009 + 31524193 = 31525202

Showing the first eight; more decompositions exist.
