Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491666, here are decompositions:

67 + 33491599 = 33491666
73 + 33491593 = 33491666
97 + 33491569 = 33491666
199 + 33491467 = 33491666
433 + 33491233 = 33491666
463 + 33491203 = 33491666
739 + 33490927 = 33491666
823 + 33490843 = 33491666

Showing the first eight; more decompositions exist.
