Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71894, here are decompositions:
- 7 + 71887 = 71894
- 13 + 71881 = 71894
- 73 + 71821 = 71894
- 181 + 71713 = 71894
- 223 + 71671 = 71894
- 331 + 71563 = 71894
- 367 + 71527 = 71894
- 421 + 71473 = 71894
Showing the first eight; more decompositions exist.
