Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19140, here are decompositions:
- 19 + 19121 = 19140
- 53 + 19087 = 19140
- 59 + 19081 = 19140
- 61 + 19079 = 19140
- 67 + 19073 = 19140
- 71 + 19069 = 19140
- 89 + 19051 = 19140
- 103 + 19037 = 19140
Showing the first eight; more decompositions exist.
