Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77184, here are decompositions:
- 13 + 77171 = 77184
- 17 + 77167 = 77184
- 31 + 77153 = 77184
- 43 + 77141 = 77184
- 47 + 77137 = 77184
- 83 + 77101 = 77184
- 103 + 77081 = 77184
- 137 + 77047 = 77184
Showing the first eight; more decompositions exist.
