Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540780, here are decompositions:

17 + 33540763 = 33540780
67 + 33540713 = 33540780
73 + 33540707 = 33540780
83 + 33540697 = 33540780
89 + 33540691 = 33540780
157 + 33540623 = 33540780
173 + 33540607 = 33540780
193 + 33540587 = 33540780

Showing the first eight; more decompositions exist.
