Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527212, here are decompositions:

19 + 31527193 = 31527212
61 + 31527151 = 31527212
103 + 31527109 = 31527212
271 + 31526941 = 31527212
313 + 31526899 = 31527212
331 + 31526881 = 31527212
349 + 31526863 = 31527212
421 + 31526791 = 31527212

Showing the first eight; more decompositions exist.
