Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33536840, here are decompositions:

31 + 33536809 = 33536840
163 + 33536677 = 33536840
307 + 33536533 = 33536840
433 + 33536407 = 33536840
769 + 33536071 = 33536840
811 + 33536029 = 33536840
829 + 33536011 = 33536840
853 + 33535987 = 33536840

Showing the first eight; more decompositions exist.
