Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529178, here are decompositions:

61 + 529117 = 529178
127 + 529051 = 529178
151 + 529027 = 529178
211 + 528967 = 529178
367 + 528811 = 529178
379 + 528799 = 529178
487 + 528691 = 529178
499 + 528679 = 529178

Showing the first eight; more decompositions exist.
