Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 60640, here are decompositions:
- 3 + 60637 = 60640
- 17 + 60623 = 60640
- 23 + 60617 = 60640
- 29 + 60611 = 60640
- 101 + 60539 = 60640
- 113 + 60527 = 60640
- 131 + 60509 = 60640
- 191 + 60449 = 60640
Showing the first eight; more decompositions exist.
