Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55290, here are decompositions:

31 + 55259 = 55290
41 + 55249 = 55290
47 + 55243 = 55290
61 + 55229 = 55290
71 + 55219 = 55290
73 + 55217 = 55290
83 + 55207 = 55290
89 + 55201 = 55290

Showing the first eight; more decompositions exist.
