Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493886, here are decompositions:

13 + 493873 = 493886
73 + 493813 = 493886
79 + 493807 = 493886
109 + 493777 = 493886
139 + 493747 = 493886
157 + 493729 = 493886
193 + 493693 = 493886
229 + 493657 = 493886

Showing the first eight; more decompositions exist.
