Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102, here are decompositions:
- 5 + 97 = 102
- 13 + 89 = 102
- 19 + 83 = 102
- 23 + 79 = 102
- 29 + 73 = 102
- 31 + 71 = 102
- 41 + 61 = 102
- 43 + 59 = 102
Showing the first eight; more decompositions exist.
