Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55982, here are decompositions:

61 + 55921 = 55982
79 + 55903 = 55982
139 + 55843 = 55982
163 + 55819 = 55982
271 + 55711 = 55982
349 + 55633 = 55982
373 + 55609 = 55982
379 + 55603 = 55982

Showing the first eight; more decompositions exist.
