Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15936, here are decompositions:
- 13 + 15923 = 15936
- 17 + 15919 = 15936
- 23 + 15913 = 15936
- 29 + 15907 = 15936
- 47 + 15889 = 15936
- 59 + 15877 = 15936
- 113 + 15823 = 15936
- 127 + 15809 = 15936
Showing the first eight; more decompositions exist.
