Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56806, here are decompositions:

23 + 56783 = 56806
59 + 56747 = 56806
173 + 56633 = 56806
263 + 56543 = 56806
317 + 56489 = 56806
353 + 56453 = 56806
389 + 56417 = 56806
557 + 56249 = 56806

Showing the first eight; more decompositions exist.
