Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521770, here are decompositions:

3 + 521767 = 521770
17 + 521753 = 521770
47 + 521723 = 521770
101 + 521669 = 521770
113 + 521657 = 521770
167 + 521603 = 521770
233 + 521537 = 521770
251 + 521519 = 521770

Showing the first eight; more decompositions exist.
