Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19370, here are decompositions:
- 37 + 19333 = 19370
- 61 + 19309 = 19370
- 97 + 19273 = 19370
- 103 + 19267 = 19370
- 139 + 19231 = 19370
- 151 + 19219 = 19370
- 157 + 19213 = 19370
- 163 + 19207 = 19370
Showing the first eight; more decompositions exist.
