Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529890, here are decompositions:

19 + 529871 = 529890
43 + 529847 = 529890
61 + 529829 = 529890
71 + 529819 = 529890
79 + 529811 = 529890
83 + 529807 = 529890
139 + 529751 = 529890
149 + 529741 = 529890

Showing the first eight; more decompositions exist.
