Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15960, here are decompositions:
- 23 + 15937 = 15960
- 37 + 15923 = 15960
- 41 + 15919 = 15960
- 47 + 15913 = 15960
- 53 + 15907 = 15960
- 59 + 15901 = 15960
- 71 + 15889 = 15960
- 73 + 15887 = 15960
Showing the first eight; more decompositions exist.
