Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89100, here are decompositions:
- 13 + 89087 = 89100
- 17 + 89083 = 89100
- 29 + 89071 = 89100
- 31 + 89069 = 89100
- 43 + 89057 = 89100
- 59 + 89041 = 89100
- 79 + 89021 = 89100
- 83 + 89017 = 89100
Showing the first eight; more decompositions exist.
