Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71672, here are decompositions:
- 79 + 71593 = 71672
- 103 + 71569 = 71672
- 109 + 71563 = 71672
- 193 + 71479 = 71672
- 199 + 71473 = 71672
- 229 + 71443 = 71672
- 283 + 71389 = 71672
- 313 + 71359 = 71672
Showing the first eight; more decompositions exist.
