Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72074, here are decompositions:
- 31 + 72043 = 72074
- 43 + 72031 = 72074
- 103 + 71971 = 72074
- 127 + 71947 = 72074
- 157 + 71917 = 72074
- 193 + 71881 = 72074
- 313 + 71761 = 72074
- 367 + 71707 = 72074
Showing the first eight; more decompositions exist.
