Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123854, here are decompositions:

37 + 123817 = 123854
67 + 123787 = 123854
97 + 123757 = 123854
127 + 123727 = 123854
193 + 123661 = 123854
223 + 123631 = 123854
271 + 123583 = 123854
307 + 123547 = 123854

Showing the first eight; more decompositions exist.
