Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5780, here are decompositions:

31 + 5749 = 5780
37 + 5743 = 5780
43 + 5737 = 5780
79 + 5701 = 5780
97 + 5683 = 5780
127 + 5653 = 5780
139 + 5641 = 5780
157 + 5623 = 5780

Showing the first eight; more decompositions exist.
