Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540172, here are decompositions:

89 + 33540083 = 33540172
101 + 33540071 = 33540172
233 + 33539939 = 33540172
389 + 33539783 = 33540172
401 + 33539771 = 33540172
431 + 33539741 = 33540172
503 + 33539669 = 33540172
509 + 33539663 = 33540172

Showing the first eight; more decompositions exist.
