Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65158, here are decompositions:
- 11 + 65147 = 65158
- 17 + 65141 = 65158
- 29 + 65129 = 65158
- 47 + 65111 = 65158
- 59 + 65099 = 65158
- 131 + 65027 = 65158
- 239 + 64919 = 65158
- 257 + 64901 = 65158
Showing the first eight; more decompositions exist.
