Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79666, here are decompositions:

53 + 79613 = 79666
107 + 79559 = 79666
173 + 79493 = 79666
233 + 79433 = 79666
239 + 79427 = 79666
269 + 79397 = 79666
317 + 79349 = 79666
347 + 79319 = 79666

Showing the first eight; more decompositions exist.
