Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561890, here are decompositions:

13 + 33561877 = 33561890
73 + 33561817 = 33561890
139 + 33561751 = 33561890
211 + 33561679 = 33561890
283 + 33561607 = 33561890
331 + 33561559 = 33561890
421 + 33561469 = 33561890
547 + 33561343 = 33561890

Showing the first eight; more decompositions exist.
