Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73170, here are decompositions:
- 29 + 73141 = 73170
- 37 + 73133 = 73170
- 43 + 73127 = 73170
- 79 + 73091 = 73170
- 107 + 73063 = 73170
- 109 + 73061 = 73170
- 127 + 73043 = 73170
- 131 + 73039 = 73170
Showing the first eight; more decompositions exist.
