Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 62720, here are decompositions:
- 19 + 62701 = 62720
- 37 + 62683 = 62720
- 61 + 62659 = 62720
- 67 + 62653 = 62720
- 103 + 62617 = 62720
- 139 + 62581 = 62720
- 157 + 62563 = 62720
- 181 + 62539 = 62720
Showing the first eight; more decompositions exist.
