Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526912, here are decompositions:

13 + 31526899 = 31526912
19 + 31526893 = 31526912
31 + 31526881 = 31526912
103 + 31526809 = 31526912
139 + 31526773 = 31526912
163 + 31526749 = 31526912
181 + 31526731 = 31526912
199 + 31526713 = 31526912

Showing the first eight; more decompositions exist.
