Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491664, here are decompositions:

23 + 33491641 = 33491664
43 + 33491621 = 33491664
61 + 33491603 = 33491664
71 + 33491593 = 33491664
97 + 33491567 = 33491664
103 + 33491561 = 33491664
127 + 33491537 = 33491664
131 + 33491533 = 33491664

Showing the first eight; more decompositions exist.
