Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523162, here are decompositions:

53 + 523109 = 523162
113 + 523049 = 523162
131 + 523031 = 523162
173 + 522989 = 523162
281 + 522881 = 523162
401 + 522761 = 523162
443 + 522719 = 523162
503 + 522659 = 523162

Showing the first eight; more decompositions exist.
