Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71678, here are decompositions:

7 + 71671 = 71678
31 + 71647 = 71678
109 + 71569 = 71678
127 + 71551 = 71678
151 + 71527 = 71678
199 + 71479 = 71678
241 + 71437 = 71678
331 + 71347 = 71678

Showing the first eight; more decompositions exist.
