Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521126, here are decompositions:

7 + 521119 = 521126
19 + 521107 = 521126
79 + 521047 = 521126
103 + 521023 = 521126
157 + 520969 = 521126
163 + 520963 = 521126
313 + 520813 = 521126
367 + 520759 = 521126

Showing the first eight; more decompositions exist.
