Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540990, here are decompositions:

11 + 33540979 = 33540990
17 + 33540973 = 33540990
19 + 33540971 = 33540990
23 + 33540967 = 33540990
29 + 33540961 = 33540990
59 + 33540931 = 33540990
71 + 33540919 = 33540990
89 + 33540901 = 33540990

Showing the first eight; more decompositions exist.
