Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55720, here are decompositions:

3 + 55717 = 55720
23 + 55697 = 55720
29 + 55691 = 55720
47 + 55673 = 55720
53 + 55667 = 55720
59 + 55661 = 55720
89 + 55631 = 55720
101 + 55619 = 55720

Showing the first eight; more decompositions exist.
