Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537940, here are decompositions:

41 + 33537899 = 33537940
83 + 33537857 = 33537940
101 + 33537839 = 33537940
131 + 33537809 = 33537940
173 + 33537767 = 33537940
239 + 33537701 = 33537940
251 + 33537689 = 33537940
257 + 33537683 = 33537940

Showing the first eight; more decompositions exist.
