Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531116, here are decompositions:

13 + 531103 = 531116
37 + 531079 = 531116
73 + 531043 = 531116
127 + 530989 = 531116
139 + 530977 = 531116
283 + 530833 = 531116
349 + 530767 = 531116
373 + 530743 = 531116

Showing the first eight; more decompositions exist.
