Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105344, here are decompositions:

3 + 105341 = 105344
7 + 105337 = 105344
13 + 105331 = 105344
67 + 105277 = 105344
307 + 105037 = 105344
313 + 105031 = 105344
373 + 104971 = 105344
397 + 104947 = 105344

Showing the first eight; more decompositions exist.
