Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72150, here are decompositions:
- 11 + 72139 = 72150
- 41 + 72109 = 72150
- 47 + 72103 = 72150
- 59 + 72091 = 72150
- 61 + 72089 = 72150
- 73 + 72077 = 72150
- 97 + 72053 = 72150
- 103 + 72047 = 72150
Showing the first eight; more decompositions exist.
