Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7140, here are decompositions:
- 11 + 7129 = 7140
- 13 + 7127 = 7140
- 19 + 7121 = 7140
- 31 + 7109 = 7140
- 37 + 7103 = 7140
- 61 + 7079 = 7140
- 71 + 7069 = 7140
- 83 + 7057 = 7140
Showing the first eight; more decompositions exist.
