Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56872, here are decompositions:

29 + 56843 = 56872
59 + 56813 = 56872
89 + 56783 = 56872
191 + 56681 = 56872
239 + 56633 = 56872
281 + 56591 = 56872
353 + 56519 = 56872
383 + 56489 = 56872

Showing the first eight; more decompositions exist.
