Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7144, here are decompositions:
- 17 + 7127 = 7144
- 23 + 7121 = 7144
- 41 + 7103 = 7144
- 101 + 7043 = 7144
- 131 + 7013 = 7144
- 167 + 6977 = 7144
- 173 + 6971 = 7144
- 197 + 6947 = 7144
Showing the first eight; more decompositions exist.
