Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19400, here are decompositions:
- 13 + 19387 = 19400
- 19 + 19381 = 19400
- 67 + 19333 = 19400
- 127 + 19273 = 19400
- 151 + 19249 = 19400
- 163 + 19237 = 19400
- 181 + 19219 = 19400
- 193 + 19207 = 19400
Showing the first eight; more decompositions exist.
