Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526908, here are decompositions:

5 + 31526903 = 31526908
29 + 31526879 = 31526908
89 + 31526819 = 31526908
131 + 31526777 = 31526908
137 + 31526771 = 31526908
239 + 31526669 = 31526908
419 + 31526489 = 31526908
431 + 31526477 = 31526908

Showing the first eight; more decompositions exist.
