Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55722, here are decompositions:

5 + 55717 = 55722
11 + 55711 = 55722
31 + 55691 = 55722
41 + 55681 = 55722
59 + 55663 = 55722
61 + 55661 = 55722
83 + 55639 = 55722
89 + 55633 = 55722

Showing the first eight; more decompositions exist.
