Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56878, here are decompositions:

5 + 56873 = 56878
71 + 56807 = 56878
131 + 56747 = 56878
167 + 56711 = 56878
191 + 56687 = 56878
197 + 56681 = 56878
281 + 56597 = 56878
347 + 56531 = 56878

Showing the first eight; more decompositions exist.
