Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77206, here are decompositions:

5 + 77201 = 77206
53 + 77153 = 77206
113 + 77093 = 77206
137 + 77069 = 77206
257 + 76949 = 77206
263 + 76943 = 77206
293 + 76913 = 77206
359 + 76847 = 77206

Showing the first eight; more decompositions exist.
