Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33544420, here are decompositions:

23 + 33544397 = 33544420
83 + 33544337 = 33544420
89 + 33544331 = 33544420
113 + 33544307 = 33544420
197 + 33544223 = 33544420
251 + 33544169 = 33544420
293 + 33544127 = 33544420
419 + 33544001 = 33544420

Showing the first eight; more decompositions exist.
