Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73140, here are decompositions:
- 7 + 73133 = 73140
- 13 + 73127 = 73140
- 19 + 73121 = 73140
- 61 + 73079 = 73140
- 79 + 73061 = 73140
- 97 + 73043 = 73140
- 101 + 73039 = 73140
- 103 + 73037 = 73140
Showing the first eight; more decompositions exist.
