Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615690, here are decompositions:

19 + 33615671 = 33615690
23 + 33615667 = 33615690
29 + 33615661 = 33615690
41 + 33615649 = 33615690
47 + 33615643 = 33615690
61 + 33615629 = 33615690
67 + 33615623 = 33615690
83 + 33615607 = 33615690

Showing the first eight; more decompositions exist.
