Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15924, here are decompositions:
- 5 + 15919 = 15924
- 11 + 15913 = 15924
- 17 + 15907 = 15924
- 23 + 15901 = 15924
- 37 + 15887 = 15924
- 43 + 15881 = 15924
- 47 + 15877 = 15924
- 101 + 15823 = 15924
Showing the first eight; more decompositions exist.
