Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77148, here are decompositions:
- 7 + 77141 = 77148
- 11 + 77137 = 77148
- 47 + 77101 = 77148
- 67 + 77081 = 77148
- 79 + 77069 = 77148
- 101 + 77047 = 77148
- 107 + 77041 = 77148
- 131 + 77017 = 77148
Showing the first eight; more decompositions exist.
