Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615870, here are decompositions:

17 + 33615853 = 33615870
23 + 33615847 = 33615870
47 + 33615823 = 33615870
73 + 33615797 = 33615870
97 + 33615773 = 33615870
103 + 33615767 = 33615870
109 + 33615761 = 33615870
131 + 33615739 = 33615870

Showing the first eight; more decompositions exist.
