Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523546, here are decompositions:

3 + 523543 = 523546
5 + 523541 = 523546
53 + 523493 = 523546
59 + 523487 = 523546
83 + 523463 = 523546
113 + 523433 = 523546
197 + 523349 = 523546
239 + 523307 = 523546

Showing the first eight; more decompositions exist.
