Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55772, here are decompositions:

61 + 55711 = 55772
109 + 55663 = 55772
139 + 55633 = 55772
151 + 55621 = 55772
163 + 55609 = 55772
193 + 55579 = 55772
271 + 55501 = 55772
331 + 55441 = 55772

Showing the first eight; more decompositions exist.
