Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4140, here are decompositions:
- 7 + 4133 = 4140
- 11 + 4129 = 4140
- 13 + 4127 = 4140
- 29 + 4111 = 4140
- 41 + 4099 = 4140
- 47 + 4093 = 4140
- 61 + 4079 = 4140
- 67 + 4073 = 4140
Showing the first eight; more decompositions exist.
