Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487820, here are decompositions:

7 + 33487813 = 33487820
61 + 33487759 = 33487820
103 + 33487717 = 33487820
139 + 33487681 = 33487820
181 + 33487639 = 33487820
199 + 33487621 = 33487820
229 + 33487591 = 33487820
241 + 33487579 = 33487820

Showing the first eight; more decompositions exist.
