Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55620, here are decompositions:

11 + 55609 = 55620
17 + 55603 = 55620
31 + 55589 = 55620
41 + 55579 = 55620
73 + 55547 = 55620
79 + 55541 = 55620
109 + 55511 = 55620
151 + 55469 = 55620

Showing the first eight; more decompositions exist.
