Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12190, here are decompositions:
- 29 + 12161 = 12190
- 41 + 12149 = 12190
- 47 + 12143 = 12190
- 71 + 12119 = 12190
- 83 + 12107 = 12190
- 89 + 12101 = 12190
- 149 + 12041 = 12190
- 179 + 12011 = 12190
Showing the first eight; more decompositions exist.
