Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528830, here are decompositions:

7 + 528823 = 528830
19 + 528811 = 528830
31 + 528799 = 528830
67 + 528763 = 528830
139 + 528691 = 528830
151 + 528679 = 528830
157 + 528673 = 528830
163 + 528667 = 528830

Showing the first eight; more decompositions exist.
