Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523626, here are decompositions:

23 + 523603 = 523626
29 + 523597 = 523626
53 + 523573 = 523626
73 + 523553 = 523626
83 + 523543 = 523626
107 + 523519 = 523626
137 + 523489 = 523626
139 + 523487 = 523626

Showing the first eight; more decompositions exist.
