Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78122, here are decompositions:

43 + 78079 = 78122
73 + 78049 = 78122
139 + 77983 = 78122
193 + 77929 = 78122
223 + 77899 = 78122
229 + 77893 = 78122
283 + 77839 = 78122
349 + 77773 = 78122

Showing the first eight; more decompositions exist.
