Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71984, here are decompositions:
- 13 + 71971 = 71984
- 37 + 71947 = 71984
- 43 + 71941 = 71984
- 67 + 71917 = 71984
- 97 + 71887 = 71984
- 103 + 71881 = 71984
- 163 + 71821 = 71984
- 223 + 71761 = 71984
Showing the first eight; more decompositions exist.
