Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18502, here are decompositions:

41 + 18461 = 18502
59 + 18443 = 18502
89 + 18413 = 18502
101 + 18401 = 18502
131 + 18371 = 18502
149 + 18353 = 18502
173 + 18329 = 18502
191 + 18311 = 18502

Showing the first eight; more decompositions exist.
