Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121826, here are decompositions:

37 + 121789 = 121826
139 + 121687 = 121826
193 + 121633 = 121826
373 + 121453 = 121826
379 + 121447 = 121826
457 + 121369 = 121826
499 + 121327 = 121826
787 + 121039 = 121826

Showing the first eight; more decompositions exist.
