Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39830, here are decompositions:
- 3 + 39827 = 39830
- 31 + 39799 = 39830
- 61 + 39769 = 39830
- 97 + 39733 = 39830
- 103 + 39727 = 39830
- 127 + 39703 = 39830
- 151 + 39679 = 39830
- 163 + 39667 = 39830
Showing the first eight; more decompositions exist.
