Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28418, here are decompositions:

7 + 28411 = 28418
31 + 28387 = 28418
67 + 28351 = 28418
109 + 28309 = 28418
139 + 28279 = 28418
199 + 28219 = 28418
307 + 28111 = 28418
331 + 28087 = 28418

Showing the first eight; more decompositions exist.
