Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72160, here are decompositions:
- 59 + 72101 = 72160
- 71 + 72089 = 72160
- 83 + 72077 = 72160
- 107 + 72053 = 72160
- 113 + 72047 = 72160
- 167 + 71993 = 72160
- 173 + 71987 = 72160
- 197 + 71963 = 72160
Showing the first eight; more decompositions exist.
