Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527036, here are decompositions:

19 + 31527017 = 31527036
83 + 31526953 = 31527036
97 + 31526939 = 31527036
109 + 31526927 = 31527036
137 + 31526899 = 31527036
157 + 31526879 = 31527036
173 + 31526863 = 31527036
227 + 31526809 = 31527036

Showing the first eight; more decompositions exist.
