Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123826, here are decompositions:

5 + 123821 = 123826
23 + 123803 = 123826
89 + 123737 = 123826
107 + 123719 = 123826
149 + 123677 = 123826
173 + 123653 = 123826
233 + 123593 = 123826
347 + 123479 = 123826

Showing the first eight; more decompositions exist.
