Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528600, here are decompositions:

41 + 528559 = 528600
73 + 528527 = 528600
89 + 528511 = 528600
109 + 528491 = 528600
113 + 528487 = 528600
131 + 528469 = 528600
167 + 528433 = 528600
181 + 528419 = 528600

Showing the first eight; more decompositions exist.
