Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531174, here are decompositions:

5 + 531169 = 531174
11 + 531163 = 531174
31 + 531143 = 531174
41 + 531133 = 531174
53 + 531121 = 531174
71 + 531103 = 531174
73 + 531101 = 531174
103 + 531071 = 531174

Showing the first eight; more decompositions exist.
