Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39960, here are decompositions:
- 7 + 39953 = 39960
- 23 + 39937 = 39960
- 31 + 39929 = 39960
- 59 + 39901 = 39960
- 73 + 39887 = 39960
- 83 + 39877 = 39960
- 97 + 39863 = 39960
- 103 + 39857 = 39960
Showing the first eight; more decompositions exist.
