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.
