Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561842, here are decompositions:

3 + 33561839 = 33561842
43 + 33561799 = 33561842
73 + 33561769 = 33561842
163 + 33561679 = 33561842
271 + 33561571 = 33561842
283 + 33561559 = 33561842
373 + 33561469 = 33561842
463 + 33561379 = 33561842

Showing the first eight; more decompositions exist.
