Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487644, here are decompositions:

5 + 33487639 = 33487644
13 + 33487631 = 33487644
23 + 33487621 = 33487644
37 + 33487607 = 33487644
53 + 33487591 = 33487644
83 + 33487561 = 33487644
101 + 33487543 = 33487644
107 + 33487537 = 33487644

Showing the first eight; more decompositions exist.
