Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33579180, here are decompositions:

29 + 33579151 = 33579180
59 + 33579121 = 33579180
67 + 33579113 = 33579180
79 + 33579101 = 33579180
113 + 33579067 = 33579180
127 + 33579053 = 33579180
211 + 33578969 = 33579180
263 + 33578917 = 33579180

Showing the first eight; more decompositions exist.
