Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15190, here are decompositions:
- 3 + 15187 = 15190
- 17 + 15173 = 15190
- 29 + 15161 = 15190
- 41 + 15149 = 15190
- 53 + 15137 = 15190
- 59 + 15131 = 15190
- 83 + 15107 = 15190
- 89 + 15101 = 15190
Showing the first eight; more decompositions exist.
