Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613890, here are decompositions:

29 + 33613861 = 33613890
31 + 33613859 = 33613890
41 + 33613849 = 33613890
43 + 33613847 = 33613890
47 + 33613843 = 33613890
61 + 33613829 = 33613890
73 + 33613817 = 33613890
83 + 33613807 = 33613890

Showing the first eight; more decompositions exist.
