Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72446, here are decompositions:
- 67 + 72379 = 72446
- 79 + 72367 = 72446
- 109 + 72337 = 72446
- 139 + 72307 = 72446
- 193 + 72253 = 72446
- 223 + 72223 = 72446
- 277 + 72169 = 72446
- 307 + 72139 = 72446
Showing the first eight; more decompositions exist.
