Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72132, here are decompositions:
- 23 + 72109 = 72132
- 29 + 72103 = 72132
- 31 + 72101 = 72132
- 41 + 72091 = 72132
- 43 + 72089 = 72132
- 59 + 72073 = 72132
- 79 + 72053 = 72132
- 89 + 72043 = 72132
Showing the first eight; more decompositions exist.
