Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527080, here are decompositions:

3 + 31527077 = 31527080
127 + 31526953 = 31527080
139 + 31526941 = 31527080
181 + 31526899 = 31527080
199 + 31526881 = 31527080
271 + 31526809 = 31527080
307 + 31526773 = 31527080
331 + 31526749 = 31527080

Showing the first eight; more decompositions exist.
