Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529880, here are decompositions:

61 + 529819 = 529880
67 + 529813 = 529880
73 + 529807 = 529880
139 + 529741 = 529880
157 + 529723 = 529880
193 + 529687 = 529880
199 + 529681 = 529880
223 + 529657 = 529880

Showing the first eight; more decompositions exist.
