Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105458, here are decompositions:

61 + 105397 = 105458
79 + 105379 = 105458
97 + 105361 = 105458
127 + 105331 = 105458
139 + 105319 = 105458
181 + 105277 = 105458
229 + 105229 = 105458
421 + 105037 = 105458

Showing the first eight; more decompositions exist.
