Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87846, here are decompositions:

13 + 87833 = 87846
43 + 87803 = 87846
53 + 87793 = 87846
79 + 87767 = 87846
103 + 87743 = 87846
107 + 87739 = 87846
127 + 87719 = 87846
149 + 87697 = 87846

Showing the first eight; more decompositions exist.
