Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491500, here are decompositions:

11 + 33491489 = 33491500
41 + 33491459 = 33491500
59 + 33491441 = 33491500
83 + 33491417 = 33491500
113 + 33491387 = 33491500
131 + 33491369 = 33491500
137 + 33491363 = 33491500
167 + 33491333 = 33491500

Showing the first eight; more decompositions exist.
