Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493140, here are decompositions:

7 + 493133 = 493140
13 + 493127 = 493140
17 + 493123 = 493140
19 + 493121 = 493140
29 + 493111 = 493140
31 + 493109 = 493140
47 + 493093 = 493140
73 + 493067 = 493140

Showing the first eight; more decompositions exist.
