Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523100, here are decompositions:

3 + 523097 = 523100
7 + 523093 = 523100
79 + 523021 = 523100
139 + 522961 = 523100
157 + 522943 = 523100
181 + 522919 = 523100
229 + 522871 = 523100
271 + 522829 = 523100

Showing the first eight; more decompositions exist.
