Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534808, here are decompositions:

7 + 31534801 = 31534808
79 + 31534729 = 31534808
139 + 31534669 = 31534808
157 + 31534651 = 31534808
211 + 31534597 = 31534808
307 + 31534501 = 31534808
367 + 31534441 = 31534808
379 + 31534429 = 31534808

Showing the first eight; more decompositions exist.
