Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100826, here are decompositions:

3 + 100823 = 100826
79 + 100747 = 100826
127 + 100699 = 100826
157 + 100669 = 100826
277 + 100549 = 100826
307 + 100519 = 100826
367 + 100459 = 100826
379 + 100447 = 100826

Showing the first eight; more decompositions exist.
