Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79870, here are decompositions:
- 3 + 79867 = 79870
- 23 + 79847 = 79870
- 29 + 79841 = 79870
- 41 + 79829 = 79870
- 47 + 79823 = 79870
- 53 + 79817 = 79870
- 59 + 79811 = 79870
- 101 + 79769 = 79870
Showing the first eight; more decompositions exist.
