Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105802, here are decompositions:

41 + 105761 = 105802
101 + 105701 = 105802
149 + 105653 = 105802
239 + 105563 = 105802
269 + 105533 = 105802
293 + 105509 = 105802
311 + 105491 = 105802
353 + 105449 = 105802

Showing the first eight; more decompositions exist.
