Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000826, here are decompositions:

103 + 1000723 = 1000826
157 + 1000669 = 1000826
373 + 1000453 = 1000826
397 + 1000429 = 1000826
433 + 1000393 = 1000826
523 + 1000303 = 1000826
577 + 1000249 = 1000826
613 + 1000213 = 1000826

Showing the first eight; more decompositions exist.
