Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10856, here are decompositions:

3 + 10853 = 10856
19 + 10837 = 10856
67 + 10789 = 10856
103 + 10753 = 10856
127 + 10729 = 10856
193 + 10663 = 10856
199 + 10657 = 10856
229 + 10627 = 10856

Showing the first eight; more decompositions exist.
