Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73240, here are decompositions:
- 3 + 73237 = 73240
- 59 + 73181 = 73240
- 107 + 73133 = 73240
- 113 + 73127 = 73240
- 149 + 73091 = 73240
- 179 + 73061 = 73240
- 197 + 73043 = 73240
- 227 + 73013 = 73240
Showing the first eight; more decompositions exist.
