Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540778, here are decompositions:

71 + 33540707 = 33540778
191 + 33540587 = 33540778
197 + 33540581 = 33540778
239 + 33540539 = 33540778
317 + 33540461 = 33540778
419 + 33540359 = 33540778
461 + 33540317 = 33540778
521 + 33540257 = 33540778

Showing the first eight; more decompositions exist.
