Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2936, here are decompositions:

19 + 2917 = 2936
79 + 2857 = 2936
103 + 2833 = 2936
139 + 2797 = 2936
223 + 2713 = 2936
229 + 2707 = 2936
277 + 2659 = 2936
379 + 2557 = 2936

Showing the first eight; more decompositions exist.
