Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491900, here are decompositions:

67 + 33491833 = 33491900
73 + 33491827 = 33491900
97 + 33491803 = 33491900
139 + 33491761 = 33491900
181 + 33491719 = 33491900
229 + 33491671 = 33491900
307 + 33491593 = 33491900
331 + 33491569 = 33491900

Showing the first eight; more decompositions exist.
