Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142794, here are decompositions:

5 + 142789 = 142794
7 + 142787 = 142794
23 + 142771 = 142794
37 + 142757 = 142794
61 + 142733 = 142794
83 + 142711 = 142794
97 + 142697 = 142794
137 + 142657 = 142794

Showing the first eight; more decompositions exist.
