Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518174, here are decompositions:

3 + 518171 = 518174
37 + 518137 = 518174
43 + 518131 = 518174
61 + 518113 = 518174
73 + 518101 = 518174
127 + 518047 = 518174
157 + 518017 = 518174
193 + 517981 = 518174

Showing the first eight; more decompositions exist.
