Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72200, here are decompositions:
- 31 + 72169 = 72200
- 61 + 72139 = 72200
- 97 + 72103 = 72200
- 109 + 72091 = 72200
- 127 + 72073 = 72200
- 157 + 72043 = 72200
- 181 + 72019 = 72200
- 229 + 71971 = 72200
Showing the first eight; more decompositions exist.
