Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33601840, here are decompositions:

23 + 33601817 = 33601840
29 + 33601811 = 33601840
71 + 33601769 = 33601840
137 + 33601703 = 33601840
191 + 33601649 = 33601840
257 + 33601583 = 33601840
281 + 33601559 = 33601840
353 + 33601487 = 33601840

Showing the first eight; more decompositions exist.
