Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526848, here are decompositions:

29 + 31526819 = 31526848
71 + 31526777 = 31526848
179 + 31526669 = 31526848
359 + 31526489 = 31526848
461 + 31526387 = 31526848
641 + 31526207 = 31526848
659 + 31526189 = 31526848
761 + 31526087 = 31526848

Showing the first eight; more decompositions exist.
