Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55782, here are decompositions:

19 + 55763 = 55782
61 + 55721 = 55782
71 + 55711 = 55782
101 + 55681 = 55782
109 + 55673 = 55782
149 + 55633 = 55782
151 + 55631 = 55782
163 + 55619 = 55782

Showing the first eight; more decompositions exist.
