Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530780, here are decompositions:

7 + 530773 = 530780
13 + 530767 = 530780
37 + 530743 = 530780
67 + 530713 = 530780
79 + 530701 = 530780
127 + 530653 = 530780
139 + 530641 = 530780
181 + 530599 = 530780

Showing the first eight; more decompositions exist.
