Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526980, here are decompositions:

41 + 31526939 = 31526980
53 + 31526927 = 31526980
59 + 31526921 = 31526980
101 + 31526879 = 31526980
227 + 31526753 = 31526980
257 + 31526723 = 31526980
311 + 31526669 = 31526980
347 + 31526633 = 31526980

Showing the first eight; more decompositions exist.
