Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537690, here are decompositions:

7 + 33537683 = 33537690
13 + 33537677 = 33537690
97 + 33537593 = 33537690
101 + 33537589 = 33537690
139 + 33537551 = 33537690
149 + 33537541 = 33537690
167 + 33537523 = 33537690
181 + 33537509 = 33537690

Showing the first eight; more decompositions exist.
