Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 62820, here are decompositions:

19 + 62801 = 62820
29 + 62791 = 62820
47 + 62773 = 62820
59 + 62761 = 62820
67 + 62753 = 62820
89 + 62731 = 62820
97 + 62723 = 62820
137 + 62683 = 62820

Showing the first eight; more decompositions exist.
