Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17972, here are decompositions:
- 13 + 17959 = 17972
- 43 + 17929 = 17972
- 61 + 17911 = 17972
- 109 + 17863 = 17972
- 181 + 17791 = 17972
- 211 + 17761 = 17972
- 223 + 17749 = 17972
- 313 + 17659 = 17972
Showing the first eight; more decompositions exist.
