Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527020, here are decompositions:

3 + 31527017 = 31527020
67 + 31526953 = 31527020
79 + 31526941 = 31527020
127 + 31526893 = 31527020
139 + 31526881 = 31527020
157 + 31526863 = 31527020
211 + 31526809 = 31527020
229 + 31526791 = 31527020

Showing the first eight; more decompositions exist.
