Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527272, here are decompositions:

19 + 31527253 = 31527272
61 + 31527211 = 31527272
79 + 31527193 = 31527272
163 + 31527109 = 31527272
331 + 31526941 = 31527272
373 + 31526899 = 31527272
379 + 31526893 = 31527272
409 + 31526863 = 31527272

Showing the first eight; more decompositions exist.
