Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78472, here are decompositions:

5 + 78467 = 78472
71 + 78401 = 78472
131 + 78341 = 78472
239 + 78233 = 78472
269 + 78203 = 78472
281 + 78191 = 78472
293 + 78179 = 78472
431 + 78041 = 78472

Showing the first eight; more decompositions exist.
