Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531038, here are decompositions:

61 + 530977 = 531038
127 + 530911 = 531038
181 + 530857 = 531038
241 + 530797 = 531038
271 + 530767 = 531038
307 + 530731 = 531038
337 + 530701 = 531038
379 + 530659 = 531038

Showing the first eight; more decompositions exist.
