Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530690, here are decompositions:

31 + 530659 = 530690
37 + 530653 = 530690
151 + 530539 = 530690
157 + 530533 = 530690
163 + 530527 = 530690
331 + 530359 = 530690
337 + 530353 = 530690
397 + 530293 = 530690

Showing the first eight; more decompositions exist.
