Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79742, here are decompositions:
- 43 + 79699 = 79742
- 73 + 79669 = 79742
- 109 + 79633 = 79742
- 163 + 79579 = 79742
- 181 + 79561 = 79742
- 193 + 79549 = 79742
- 211 + 79531 = 79742
- 331 + 79411 = 79742
Showing the first eight; more decompositions exist.
