Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27878, here are decompositions:

31 + 27847 = 27878
61 + 27817 = 27878
79 + 27799 = 27878
127 + 27751 = 27878
139 + 27739 = 27878
181 + 27697 = 27878
337 + 27541 = 27878
349 + 27529 = 27878

Showing the first eight; more decompositions exist.
