Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56890, here are decompositions:

17 + 56873 = 56890
47 + 56843 = 56890
83 + 56807 = 56890
107 + 56783 = 56890
179 + 56711 = 56890
227 + 56663 = 56890
257 + 56633 = 56890
293 + 56597 = 56890

Showing the first eight; more decompositions exist.
