Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70840, here are decompositions:
- 17 + 70823 = 70840
- 47 + 70793 = 70840
- 71 + 70769 = 70840
- 131 + 70709 = 70840
- 173 + 70667 = 70840
- 233 + 70607 = 70840
- 251 + 70589 = 70840
- 257 + 70583 = 70840
Showing the first eight; more decompositions exist.
