Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105452, here are decompositions:

3 + 105449 = 105452
73 + 105379 = 105452
79 + 105373 = 105452
199 + 105253 = 105452
223 + 105229 = 105452
241 + 105211 = 105452
421 + 105031 = 105452
433 + 105019 = 105452

Showing the first eight; more decompositions exist.
