Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72152, here are decompositions:
- 13 + 72139 = 72152
- 43 + 72109 = 72152
- 61 + 72091 = 72152
- 79 + 72073 = 72152
- 109 + 72043 = 72152
- 181 + 71971 = 72152
- 211 + 71941 = 72152
- 271 + 71881 = 72152
Showing the first eight; more decompositions exist.
