Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72560, here are decompositions:
- 13 + 72547 = 72560
- 67 + 72493 = 72560
- 79 + 72481 = 72560
- 139 + 72421 = 72560
- 181 + 72379 = 72560
- 193 + 72367 = 72560
- 223 + 72337 = 72560
- 283 + 72277 = 72560
Showing the first eight; more decompositions exist.
