Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40136, here are decompositions:
- 7 + 40129 = 40136
- 13 + 40123 = 40136
- 37 + 40099 = 40136
- 43 + 40093 = 40136
- 73 + 40063 = 40136
- 97 + 40039 = 40136
- 127 + 40009 = 40136
- 157 + 39979 = 40136
Showing the first eight; more decompositions exist.
