Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 62778, here are decompositions:

5 + 62773 = 62778
17 + 62761 = 62778
47 + 62731 = 62778
139 + 62639 = 62778
151 + 62627 = 62778
181 + 62597 = 62778
197 + 62581 = 62778
229 + 62549 = 62778

Showing the first eight; more decompositions exist.
