Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73212, here are decompositions:
- 23 + 73189 = 73212
- 31 + 73181 = 73212
- 71 + 73141 = 73212
- 79 + 73133 = 73212
- 149 + 73063 = 73212
- 151 + 73061 = 73212
- 173 + 73039 = 73212
- 193 + 73019 = 73212
Showing the first eight; more decompositions exist.
