Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180318, here are decompositions:

7 + 180311 = 180318
11 + 180307 = 180318
29 + 180289 = 180318
31 + 180287 = 180318
37 + 180281 = 180318
59 + 180259 = 180318
71 + 180247 = 180318
79 + 180239 = 180318

Showing the first eight; more decompositions exist.
