Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 62840, here are decompositions:

13 + 62827 = 62840
67 + 62773 = 62840
79 + 62761 = 62840
97 + 62743 = 62840
109 + 62731 = 62840
139 + 62701 = 62840
157 + 62683 = 62840
181 + 62659 = 62840

Showing the first eight; more decompositions exist.
