Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123974, here are decompositions:

43 + 123931 = 123974
157 + 123817 = 123974
241 + 123733 = 123974
307 + 123667 = 123974
313 + 123661 = 123974
337 + 123637 = 123974
373 + 123601 = 123974
421 + 123553 = 123974

Showing the first eight; more decompositions exist.
