Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528548, here are decompositions:

37 + 528511 = 528548
61 + 528487 = 528548
79 + 528469 = 528548
157 + 528391 = 528548
331 + 528217 = 528548
421 + 528127 = 528548
457 + 528091 = 528548
547 + 528001 = 528548

Showing the first eight; more decompositions exist.
