Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540390, here are decompositions:

17 + 33540373 = 33540390
31 + 33540359 = 33540390
47 + 33540343 = 33540390
73 + 33540317 = 33540390
83 + 33540307 = 33540390
101 + 33540289 = 33540390
113 + 33540277 = 33540390
131 + 33540259 = 33540390

Showing the first eight; more decompositions exist.
