Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19846, here are decompositions:

3 + 19843 = 19846
5 + 19841 = 19846
53 + 19793 = 19846
83 + 19763 = 19846
107 + 19739 = 19846
137 + 19709 = 19846
149 + 19697 = 19846
263 + 19583 = 19846

Showing the first eight; more decompositions exist.
