Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531044, here are decompositions:

61 + 530983 = 531044
67 + 530977 = 531044
97 + 530947 = 531044
193 + 530851 = 531044
211 + 530833 = 531044
271 + 530773 = 531044
277 + 530767 = 531044
313 + 530731 = 531044

Showing the first eight; more decompositions exist.
