Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530812, here are decompositions:

5 + 530807 = 530812
59 + 530753 = 530812
71 + 530741 = 530812
101 + 530711 = 530812
263 + 530549 = 530812
281 + 530531 = 530812
311 + 530501 = 530812
383 + 530429 = 530812

Showing the first eight; more decompositions exist.
