Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508830, here are decompositions:

13 + 33508817 = 33508830
23 + 33508807 = 33508830
29 + 33508801 = 33508830
97 + 33508733 = 33508830
101 + 33508729 = 33508830
109 + 33508721 = 33508830
191 + 33508639 = 33508830
211 + 33508619 = 33508830

Showing the first eight; more decompositions exist.
