Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493730, here are decompositions:

19 + 493711 = 493730
37 + 493693 = 493730
73 + 493657 = 493730
103 + 493627 = 493730
109 + 493621 = 493730
151 + 493579 = 493730
157 + 493573 = 493730
163 + 493567 = 493730

Showing the first eight; more decompositions exist.
