Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521956, here are decompositions:

53 + 521903 = 521956
59 + 521897 = 521956
137 + 521819 = 521956
167 + 521789 = 521956
179 + 521777 = 521956
233 + 521723 = 521956
263 + 521693 = 521956
353 + 521603 = 521956

Showing the first eight; more decompositions exist.
