Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105434, here are decompositions:

37 + 105397 = 105434
61 + 105373 = 105434
67 + 105367 = 105434
73 + 105361 = 105434
97 + 105337 = 105434
103 + 105331 = 105434
157 + 105277 = 105434
181 + 105253 = 105434

Showing the first eight; more decompositions exist.
