Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105928, here are decompositions:

29 + 105899 = 105928
167 + 105761 = 105928
227 + 105701 = 105928
401 + 105527 = 105928
419 + 105509 = 105928
461 + 105467 = 105928
479 + 105449 = 105928
491 + 105437 = 105928

Showing the first eight; more decompositions exist.
