Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121874, here are decompositions:

7 + 121867 = 121874
31 + 121843 = 121874
163 + 121711 = 121874
241 + 121633 = 121874
283 + 121591 = 121874
367 + 121507 = 121874
373 + 121501 = 121874
421 + 121453 = 121874

Showing the first eight; more decompositions exist.
