Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6318, here are decompositions:

7 + 6311 = 6318
17 + 6301 = 6318
19 + 6299 = 6318
31 + 6287 = 6318
41 + 6277 = 6318
47 + 6271 = 6318
61 + 6257 = 6318
71 + 6247 = 6318

Showing the first eight; more decompositions exist.
