Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19378, here are decompositions:
- 5 + 19373 = 19378
- 59 + 19319 = 19378
- 89 + 19289 = 19378
- 167 + 19211 = 19378
- 197 + 19181 = 19378
- 239 + 19139 = 19378
- 257 + 19121 = 19378
- 347 + 19031 = 19378
Showing the first eight; more decompositions exist.
