Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89180, here are decompositions:
- 43 + 89137 = 89180
- 61 + 89119 = 89180
- 67 + 89113 = 89180
- 73 + 89107 = 89180
- 79 + 89101 = 89180
- 97 + 89083 = 89180
- 109 + 89071 = 89180
- 139 + 89041 = 89180
Showing the first eight; more decompositions exist.
