Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 62780, here are decompositions:

7 + 62773 = 62780
19 + 62761 = 62780
37 + 62743 = 62780
79 + 62701 = 62780
97 + 62683 = 62780
127 + 62653 = 62780
163 + 62617 = 62780
199 + 62581 = 62780

Showing the first eight; more decompositions exist.
