Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561100, here are decompositions:

11 + 33561089 = 33561100
47 + 33561053 = 33561100
101 + 33560999 = 33561100
149 + 33560951 = 33561100
257 + 33560843 = 33561100
359 + 33560741 = 33561100
383 + 33560717 = 33561100
389 + 33560711 = 33561100

Showing the first eight; more decompositions exist.
