Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581390, here are decompositions:

61 + 33581329 = 33581390
103 + 33581287 = 33581390
109 + 33581281 = 33581390
127 + 33581263 = 33581390
181 + 33581209 = 33581390
379 + 33581011 = 33581390
397 + 33580993 = 33581390
433 + 33580957 = 33581390

Showing the first eight; more decompositions exist.
