Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81498, here are decompositions:

41 + 81457 = 81498
59 + 81439 = 81498
89 + 81409 = 81498
97 + 81401 = 81498
127 + 81371 = 81498
139 + 81359 = 81498
149 + 81349 = 81498
167 + 81331 = 81498

Showing the first eight; more decompositions exist.
