Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55786, here are decompositions:

23 + 55763 = 55786
53 + 55733 = 55786
89 + 55697 = 55786
113 + 55673 = 55786
167 + 55619 = 55786
197 + 55589 = 55786
239 + 55547 = 55786
257 + 55529 = 55786

Showing the first eight; more decompositions exist.
