Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526940, here are decompositions:

13 + 31526927 = 31526940
19 + 31526921 = 31526940
37 + 31526903 = 31526940
41 + 31526899 = 31526940
47 + 31526893 = 31526940
59 + 31526881 = 31526940
61 + 31526879 = 31526940
131 + 31526809 = 31526940

Showing the first eight; more decompositions exist.
