Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521132, here are decompositions:

13 + 521119 = 521132
109 + 521023 = 521132
151 + 520981 = 521132
163 + 520969 = 521132
211 + 520921 = 521132
373 + 520759 = 521132
433 + 520699 = 521132
499 + 520633 = 521132

Showing the first eight; more decompositions exist.
