Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523700, here are decompositions:

19 + 523681 = 523700
31 + 523669 = 523700
43 + 523657 = 523700
61 + 523639 = 523700
97 + 523603 = 523700
103 + 523597 = 523700
127 + 523573 = 523700
157 + 523543 = 523700

Showing the first eight; more decompositions exist.
