Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531302, here are decompositions:

3 + 531299 = 531302
73 + 531229 = 531302
139 + 531163 = 531302
181 + 531121 = 531302
199 + 531103 = 531302
223 + 531079 = 531302
313 + 530989 = 531302
433 + 530869 = 531302

Showing the first eight; more decompositions exist.
