Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530906, here are decompositions:

37 + 530869 = 530906
73 + 530833 = 530906
109 + 530797 = 530906
139 + 530767 = 530906
163 + 530743 = 530906
193 + 530713 = 530906
307 + 530599 = 530906
367 + 530539 = 530906

Showing the first eight; more decompositions exist.
