Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534850, here are decompositions:

19 + 31534831 = 31534850
31 + 31534819 = 31534850
97 + 31534753 = 31534850
181 + 31534669 = 31534850
199 + 31534651 = 31534850
307 + 31534543 = 31534850
349 + 31534501 = 31534850
367 + 31534483 = 31534850

Showing the first eight; more decompositions exist.
