Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55802, here are decompositions:

3 + 55799 = 55802
139 + 55663 = 55802
163 + 55639 = 55802
181 + 55621 = 55802
193 + 55609 = 55802
199 + 55603 = 55802
223 + 55579 = 55802
421 + 55381 = 55802

Showing the first eight; more decompositions exist.
