Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105236, here are decompositions:

7 + 105229 = 105236
37 + 105199 = 105236
139 + 105097 = 105236
199 + 105037 = 105236
277 + 104959 = 105236
283 + 104953 = 105236
367 + 104869 = 105236
409 + 104827 = 105236

Showing the first eight; more decompositions exist.
