Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27788, here are decompositions:

37 + 27751 = 27788
97 + 27691 = 27788
157 + 27631 = 27788
307 + 27481 = 27788
331 + 27457 = 27788
379 + 27409 = 27788
421 + 27367 = 27788
547 + 27241 = 27788

Showing the first eight; more decompositions exist.
