Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 60840, here are decompositions:
- 19 + 60821 = 60840
- 29 + 60811 = 60840
- 47 + 60793 = 60840
- 61 + 60779 = 60840
- 67 + 60773 = 60840
- 79 + 60761 = 60840
- 83 + 60757 = 60840
- 103 + 60737 = 60840
Showing the first eight; more decompositions exist.
