Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76556, here are decompositions:

13 + 76543 = 76556
19 + 76537 = 76556
37 + 76519 = 76556
223 + 76333 = 76556
307 + 76249 = 76556
313 + 76243 = 76556
349 + 76207 = 76556
397 + 76159 = 76556

Showing the first eight; more decompositions exist.
