Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10780, here are decompositions:

41 + 10739 = 10780
47 + 10733 = 10780
71 + 10709 = 10780
89 + 10691 = 10780
113 + 10667 = 10780
149 + 10631 = 10780
167 + 10613 = 10780
173 + 10607 = 10780

Showing the first eight; more decompositions exist.
