Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528074, here are decompositions:

31 + 528043 = 528074
61 + 528013 = 528074
73 + 528001 = 528074
193 + 527881 = 528074
223 + 527851 = 528074
271 + 527803 = 528074
373 + 527701 = 528074
541 + 527533 = 528074

Showing the first eight; more decompositions exist.
