Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40070, here are decompositions:
- 7 + 40063 = 40070
- 31 + 40039 = 40070
- 61 + 40009 = 40070
- 193 + 39877 = 40070
- 223 + 39847 = 40070
- 229 + 39841 = 40070
- 241 + 39829 = 40070
- 271 + 39799 = 40070
Showing the first eight; more decompositions exist.
