Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537840, here are decompositions:

31 + 33537809 = 33537840
43 + 33537797 = 33537840
71 + 33537769 = 33537840
73 + 33537767 = 33537840
131 + 33537709 = 33537840
139 + 33537701 = 33537840
151 + 33537689 = 33537840
157 + 33537683 = 33537840

Showing the first eight; more decompositions exist.
