Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528944, here are decompositions:

61 + 528883 = 528944
67 + 528877 = 528944
181 + 528763 = 528944
271 + 528673 = 528944
277 + 528667 = 528944
313 + 528631 = 528944
433 + 528511 = 528944
457 + 528487 = 528944

Showing the first eight; more decompositions exist.
