Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81846, here are decompositions:

7 + 81839 = 81846
29 + 81817 = 81846
47 + 81799 = 81846
73 + 81773 = 81846
97 + 81749 = 81846
109 + 81737 = 81846
139 + 81707 = 81846
157 + 81689 = 81846

Showing the first eight; more decompositions exist.
