Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72136, here are decompositions:
- 47 + 72089 = 72136
- 59 + 72077 = 72136
- 83 + 72053 = 72136
- 89 + 72047 = 72136
- 137 + 71999 = 72136
- 149 + 71987 = 72136
- 173 + 71963 = 72136
- 227 + 71909 = 72136
Showing the first eight; more decompositions exist.
