Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555830, here are decompositions:

13 + 33555817 = 33555830
31 + 33555799 = 33555830
73 + 33555757 = 33555830
79 + 33555751 = 33555830
103 + 33555727 = 33555830
127 + 33555703 = 33555830
151 + 33555679 = 33555830
163 + 33555667 = 33555830

Showing the first eight; more decompositions exist.
