Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55742, here are decompositions:

31 + 55711 = 55742
61 + 55681 = 55742
79 + 55663 = 55742
103 + 55639 = 55742
109 + 55633 = 55742
139 + 55603 = 55742
163 + 55579 = 55742
241 + 55501 = 55742

Showing the first eight; more decompositions exist.
