Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33597840, here are decompositions:

13 + 33597827 = 33597840
19 + 33597821 = 33597840
37 + 33597803 = 33597840
53 + 33597787 = 33597840
79 + 33597761 = 33597840
109 + 33597731 = 33597840
131 + 33597709 = 33597840
149 + 33597691 = 33597840

Showing the first eight; more decompositions exist.
