Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81246, here are decompositions:

7 + 81239 = 81246
13 + 81233 = 81246
23 + 81223 = 81246
43 + 81203 = 81246
47 + 81199 = 81246
73 + 81173 = 81246
83 + 81163 = 81246
89 + 81157 = 81246

Showing the first eight; more decompositions exist.
