Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105898, here are decompositions:

131 + 105767 = 105898
137 + 105761 = 105898
197 + 105701 = 105898
389 + 105509 = 105898
431 + 105467 = 105898
449 + 105449 = 105898
461 + 105437 = 105898
491 + 105407 = 105898

Showing the first eight; more decompositions exist.
