Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78342, here are decompositions:

31 + 78311 = 78342
41 + 78301 = 78342
59 + 78283 = 78342
83 + 78259 = 78342
101 + 78241 = 78342
109 + 78233 = 78342
113 + 78229 = 78342
139 + 78203 = 78342

Showing the first eight; more decompositions exist.
