Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529878, here are decompositions:

7 + 529871 = 529878
31 + 529847 = 529878
59 + 529819 = 529878
67 + 529811 = 529878
71 + 529807 = 529878
127 + 529751 = 529878
131 + 529747 = 529878
137 + 529741 = 529878

Showing the first eight; more decompositions exist.
