Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73218, here are decompositions:
- 29 + 73189 = 73218
- 37 + 73181 = 73218
- 97 + 73121 = 73218
- 127 + 73091 = 73218
- 139 + 73079 = 73218
- 157 + 73061 = 73218
- 179 + 73039 = 73218
- 181 + 73037 = 73218
Showing the first eight; more decompositions exist.
