Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530842, here are decompositions:

5 + 530837 = 530842
89 + 530753 = 530842
101 + 530741 = 530842
131 + 530711 = 530842
149 + 530693 = 530842
173 + 530669 = 530842
233 + 530609 = 530842
239 + 530603 = 530842

Showing the first eight; more decompositions exist.
