Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15954, here are decompositions:
- 17 + 15937 = 15954
- 31 + 15923 = 15954
- 41 + 15913 = 15954
- 47 + 15907 = 15954
- 53 + 15901 = 15954
- 67 + 15887 = 15954
- 73 + 15881 = 15954
- 131 + 15823 = 15954
Showing the first eight; more decompositions exist.
